Island of Viscan

The Island of Viscan is an isolated island located in a region known for its volcanic activity in the southern part of the Lucidian Ocean.

Description
Viscan has a mountain in the center of a very thick jungle, in which there is a cavern system extending deep below the ground.

Forest
Viscan has a jungle like forest. When Vox Machina visited the forest the outer edge was healthy and green, but as they traveled further in towards the mountain, the trees were gray and withered. Keyleth was able to determine that this appeared to be a necromantic blight that had rapidly withered the trees, and that it had happened some time ago.

There were a few patches of 15-foot oval area of hollow earth, which were created when subterranean caverns collapsed by an explosion of magical energy beneath the earth. Even though there was no space, it erodes the earth from its magic presence, whether it just completely disintegrates or destroys portions of the earth, it leaves this very, very unstable portion of ground.

Mountain
It was a moderate-sized mountain, about 600 feet tall at its apex. The surface and most of the rock follows the familiar pattern of tectonic shift that had broken and cracked in places that, over hundreds and thousands of years, just settled into its natural state.

Mountain Entrance
There was one section of rock just 200 feet from the base where the texture of the natural lines of the rock, that was in a different direction. There was a very large heavy rock, 20-30 feet wide, that was jammed into an entranceway. This rock had a number of large holes peppered over the surface. Each one of these holes was a pierced intrusion upon the rock. And they were clustered in places, these were respective to the claws size of a very large dragon, some of them were more weathered than others. This boulder had been placed and pulled back and placed many times throughout the years.

Mountain tunnel
The Tunnel was 15-foot-wide and 12-foot-tall. The rock walls of the pathway were rough, but appeared to been intentionally carved for a purpose. There was a layer of heavy untouched dust across the ground, amongst the dust and pebbles on the floor, there were a number of scattered shards of years old blackened bone across the floor. About 100 feet in, the tunnel began to curve to the left and descend down.

Eventually, as the grade continues downward, the hallway opens up, and the walls began having slight shapes of details to them. There were small shelves or alcoves every 20 feet, little bits of rock jutting out, and small little cubbies along the walls.

The first small shelf on the right had a number of dust-covered cluster of candles that had long burned and melted into dripping wax that pours down the side of its shelf. On the left there was a shelf with two mostly melted candles and a human skull with an undead energy about it. On the opposite side of the tunnel there was a shelf that had a couple of small books that were put off to the side, and what looks like a small wooden box. The next shelf had some sort of a mummified raccoon-type creature that was propped up. After another 50 feet the tunnel opened up into a hexagonal room.

Hexagonal chamber
In this room there was stonework over the entire floor with a large iron door. The chamber's height was about 25 feet. In the center of this chamber, 15 feet away from where the iron door was, there was a platform about five to six feet up where a dark green marble pillar stood about chest-height. On top of the pillar there was a roughly forged bowl of iron that was imperfect and was bolted to the top of this pillar. On the bottom of the bowl there was a very faint residue what was dried a long time ago. Also on the shelf there was a cold iron brazier that was unburnt and had a bunch of dried tinder in it. Off to the right, there was a shelf that contained a very large leather-bound tome with no text on the spine. When reading the page in the tome the text got smaller and smaller until it was microscopic.

In each hallway that led to this room were two human skulls; when they were activated they would turn in to four cackling, floating, flame-wreathed skulls that could attack.

Staircase
Five feet above the staircase there was a celling with a glyph on it. Which would activated when someone descend the stairs. At the bottom of the stairs there were a cluster of four-foot-long deep brown or maroon-colored iron spikes that were all jutting upward in slightly off-kilter directions, and there was a heavy pile of splintered bones and long-mummified dead corpses that were piled up at the base of these spikes, some still impaled, many of which had slowly rotted and fallen apart.

Reversed-gravity bridge trap
The tunnel leading from the staircase was 20 feet wide and 15 feet tall. The walls were chiseled roughly, about 30 feet in it ended at a cross-section of a very deep ravine, both above and below. There was an underground chasm that stretched both to the right and left. On the bottom of the ravine there were nearly skeletal humanoid bodies. The chasm was about 60 feet across to the other side, and there was a taut rope bridge bolted to each side leading across. When walking across this bridge gravity seemed to be reversed and undead bodies of humanoid creatures were falling up. On the other side there was another entranceway that led to another hallway.

Fountain Chamber
50 Feet down in the hallway there was a small fountain built into the center on the ground. This fountain had two bowls above each other, the upper bowl smaller than the lower. At the very top there was a humanoid face that's stretched into a ghastly, horrified expression of terror and gasp. From its mouth a small trickle of water was pouring upward, just spilling 15 feet up onto the ceiling, where it pooled and separated into cracks. The water was impacting a green emerald-like gem in the ceiling. Covering the gem would reverse the gravity in the ravine.

Hallway and Laboratory
The ceiling of the path began to grow higher, and the hall began to widen open, and splits in two directions. Portions of this hallway still had the cavern-type feel, but more sections looked like the walls were carved out at one point and had a specific purpose, but over time portions of it had fallen to disuse and ruin. The two paths eventually joined again on the other side of the large column. Where the rocky walls became just stone and the hallway opens up to a square-like chamber.

There were two cages in the corners that seemed to bear some sort of slumped, unmoving bodies inside of them. There were two pillars in the center of the room that appeared to be just strewn with various magical engravings and glyphs from top to bottom, surrounding them entirely. There were a series of bookshelves, candelabras, and chains that lined the walls. There was a large door across the back wall that was locked from the other side.

Background
In the Age of Arcanum, the island was the lair of an ancient necromancer named Opash, who built a laboratory there after he was banished from Marquet.

Prior to Opash's arrival, the island was populated by an indigenous seafaring people whose trade routes led to the north and west. They disappeared after Opash's arrival, and many sailors in the region believed that the island was cursed and was to be avoided for that reason.

Thordak lived on the island in secret after avoiding fleeing J'mon Sa Ord in Ank'harel. He used the time to rebuild himself and his domain, until attacking western Tal'Dorei about fifteen years before the events in.

Raishan fled to the Island of Viscan after the death of Thordak, taking Thordak's body and two eggs with her. Keyleth and Allura found the cavern into which Raishan had fled when they scried. In their vision, portions of cavern appeared ruined, and Keyleth sensed sort of geothermal activity in the vicinity. She also saw that the cavern led to an ancient stone laboratory.

Keyleth used Transport via Plants to bring Vox Machina, Kerrek,Lady Kima and Allura to the island. At the entrance of the mountain, she used Stone Shape to make a slight opening in the large heavy rock. Using Kima’s sword as leverage, they moved the boulder and set it in place with the Immovable rod.

In the necromancer's sanctum, Keyleth started a fire in the iron brazier with Flaming Hands which caused an explosion that destroyed the tomb. With the blood of Vex'ahlia and a basilisk put in the bowl, the iron door opened, activating the skulls. Percy exploded two skulls with Animus, Vex'ahlia cut an arrow straight through a skull causing it to crack in half, and Allura used Magic Missile to turn the last skull to ashes.

The glyph on the ceiling activated as the party went downstairs. Scanlan used Dispel Magic to dissipate the glyph.

At the gravity chasm, Vax'ildan teleported across with Whisper, Percy went across the bridge with his Boots of Spider Climbing and the Endless Rope, Allura used Dimension Door to cross with Kima, and Kerrek and Keyleth made the crossing on the Carpet of Flying. When Vex’ahlia and Pike attempted to cross the ravine, they were hit by bodies falling upward and the broom began to fall in the same direction. They were saved from falling by a Grasping Vine from Keyleth. With the help of Percy and the carpet, they made it safely to the other side of the chasm. Vex'ahlia then went back across to get Grog and Scanlan on the other side, Grog in the Raven's Slumber necklace and Scanlan on the back of the broom.

At the fountain, Allura asked for a jug and covered the gem. The party came to the conclusion that the gem controlled the direction of gravity in the ravine.

The party found Raishan in the laboratory. The two large scaled, crimson eggs were being kept on one side of the wall, and on the other side a withered and long-dead corpse of Thordak the Cinder King.

Vox Machina began their second battle against Raishan. Raishan attacked the party with multiple powerful spells, including Meteor Swarm. During the battle, Raishan killed Scanlan. Keyleth managed to hit her with a successful Feeblemind spell, preventing her from using any more spells. Nevertheless, Raishan still managed to get another kill, this time gutting Percy. Shortly after, Raishan's was killed by a fierce hammer blow from Kerrek.

After Pike revived Percy, he leaves a gate stone behind, and Vax took Scanlan's body in his arms. Allura attempted to use Teleport on the party to leave the island, but the spell failed. The party began to investigate the cause, and Grog was able to break down the door with his Titanstone Knuckles, revealing a cave-in. Pike discovered an ancient, leather-bound book, locked on one side, that Raishan had been reading. Percy took several other books. The party then did their best to destroy the laboratory with fire from Keyleth's staff, Scanlan’s Wand of Magic Missiles, and some spells from Allura, running into several more minor traps in the process. On their way out, the party encountered the flaming skulls again and defeated them with Animus, a high-level Magic Missile, and a hit from Kerrek.

Once outside Allura attempted to draw a Teleportation Circle on the ground but then vanished with a strange spark. Kima went after her. Vox Machina became suspicious and determined that something on island warped arcane transportation magic. Keyleth scried on Allura and saw that she was in the ocean, and then saw faint movement in the distance. Vex was able to reach them on her broom and bring them back to the island. Once retrieved, Keyleth used Transport via Plants to successfully bring the group back to Whitestone.
