Rumblecusp

 is a volcanic island in the Swavain Islands, southwest of Nicodranas and northwest of Urukayxl in the Lucidian Ocean. It is scheduled to be the site of TravelerCon on the 26th of Unndilar, 836 PD.

Appearance
Dominated by the volcano that gives it its name, the island's shallow white sand beaches and rare trees create a tropical paradise. At a distance, it is dominated by a wild mountain range, with thin switchbacked ridges giving it the odd appearance of an opening flower. In its center rises a massive mountain with a lazy trail of smoke drifting from its peak. The majority of the island is dense, lush jungle, surrounded by a faint ring of white sand beaches against rocky cliffs. The jungle is so dense that it seems to rise and roil with the landscape, rising up over mountain ridges. Some of the trees push up and cause strange tower-like structures that grow much larger than all the others surrounding them. The volcano itself comes to a point, with no caldera visible. There is a bit of an orange glow from a faint magma trickle near the zenith of the mountain, and a fissure from which the smoke emerges.

From the southeastern inlet, a faint mist lies over a large portion of the outer jungle, giving the island an almost dream-like quality. Beneath the water are sandbanks that wind out beyond the beach, looking like white tendrils beneath the ocean. Rising above the mist, the trees are extremely tall, a hundred or more feet up with thick trunks. A little further in, on the path toward the base of the massive central volcano of Rumblecusp, is a clearing holding a small village.

Viridian, one of the leaders of the village, described the island as the central focus of the world, home to many strange slivers of different parts of the world that create the land mass. Beneath the trees are odd landmarks that shelter dangerous beasts that might be a surprise to find on the ocean, a number of unnatural dangerous denizens. To cross the island, moving carefully, she estimated would take a few days, and about eight hours to reach the base of the volcano from the village.

Vo Village
The village, known as Vo, consists of about two dozen or more structures built across the ground and into the tree canopies themselves. There are networks of ropes and other long pulleys and cords that are bound between trees at a distance, and there are buildings held aloft about fifty or sixty feet off the ground, with bridges connecting them. Elements of it appear to be built of driftwood, or carved from local trees, or from pieces of ships that have been scavenged.

There are heavy ropes tied to the higher trunks and branches, a massive tangle of treehouses built of makeshift scavenged materials, ship parts, local lumber, and intricately woven and grown vines and dried vegetation. A third of the buildings are built up above at different levels connected by bridges. Most of the structures are supported by thick, healthy green vines, braided, entwined, and tended to hold and wrap them as it the jungle itself had risen to support and help hold the village together, structure to structure. The buildings are diverse in styles, materials, and apparent age.

A central massive tree marks the middle point of the village, lush and perhaps 200-feet tall, with numerous levels of branches. In each of these branches, the vines have grown out to clutch another small homestead almost like a hand, and all of them have connected vine bridges. It resembles a high elven establishment mixed with nature, deliberate and balanced with the natural world around it.

The Winding Core
The location from which the villagers mine beautiful gems, diamonds, and "various gifts from the land that we can refine".

The Shaded Tangle
The Shaded Tangle lies along the path towards the entrance to Vokodo’s lair within the mountain itself, a cold place where color seems to be muted, where the mists grow cold.

The Ruin
The Ruin lies far to the north on the island.

Heaven Falls
Lying to the northeast, the Heaven Falls are still a mystery to the Vo people.

Society
Only a few dozen people inhabit the island. Pono estimated there were close to seventy when the Mighty Nein arrived there.

History
The island has been populated for ten to eleven generations.

The Mighty Nein arrived on the island (fleeing from a dragon turtle) in preparation for TravelerCon upcoming in slightly over a week. They encountered several displacer beasts that were routed by two werebear inhabitants of the island, whom they befriended, and were led through the jungle to the village of the Vo people, followers of Vokodo.
