Subterranean tunnels of the Labenda Swamp

The Subterranean Tunnels of The Labenda Swamp was a network of underwater passage with occasional air pockets that was used by the Merrow in the Labenda Swamp.

Safe House Entrance
Inside of the gentleman’s safe house was a hole leading to the tunnels. The hole had chunks of rock and dirt as well as an interwoven network of roots coming down from the tree that eased climbing. There was swamp water running down the tunnel. It was about three feet wide in most places and there were claw marks where it had been dug out.

First chamber
This chamber was kidney shaped. It had a ten-foot high ceiling and a natural gravel and sand floor. There were a few outcropping walls and in the center was a small pool. The pool had brackish and thick water with four discarded humanoid skeletons at the bottom. On the other side of the kidney there was a ten square foott side pool that hid a tunnel that connected the first and the second chambers. Beside the pool there were a couple things laying on the ground:
 * A bunch of empty partially destroyed crates
 * Torn apart crocodile corpses
 * 250 gold worth of jewelry
 * 185 gold, 210 silver pieces, and 65 copper
 * Four sets of manacles
 * Two vials with a thick oily purple substance
 * A number of broken vials.
 * A well-crafted magical marble bowl of gold inlay with a curious design. The edges of the bowl shifted into five equidistant dragon heads, and each dragon had eyes of tiny gemstones. The gems were rubies, emeralds, sapphires, and diamonds. It was used as a communion device. When filled with enough blood and given the proper ritual, it was used to acquire auguries, divination, and communication across the Divine Gate with the Scaled Tyrant.

The Tunnel
The entrance of the tunnel was 5 by 10 feet and was used to travel between the chambers. The tunnel was 15 feet high with a layer of sediment on the bottom. The tunnel curved below before evening out and going for about 30-40 feet before opening up into a 20-foot pool in the second chamber.

Second Chamber
This chamber was mostly built out of natural rock, but there were elements of it that looked like it was once old mason architecture. On the edges of the chamber were stacked stones. The walls seemed to have been partially reclaimed by the ages. There were two large central pillars where stalactites and stalagmites met and created a structure in the center. There was a big pool in the middle with a weird set of stairs that stepped up to a platform on the side, and a small pool in the north of the chamber were a underwater tunnel was located. There were no passageways visible in the room; all the entrances and exits were through the various pools of water.

The Large Pool
A large portion of the floor in the second chamber was submerged in water, and different paths and avenues of it curved off and vanish and opened up to other tunnels beneath.

The Platform
On the platform was an oblong rock formation and boxes, crates, and piles of things gathered around it that looked to be:
 * Scattered bits of gold and silver and copper that were lost amongst the steps, some of them covered in dirt or mud
 * Broken pieces of nice, polished pottery with a nice glaze
 * Piles of things that have been pulled out and placed near the top of the stair
 * Remnants of crates and broken goods, littered across the rough staircase,
 * A bunch of fine silverware partially packed with mud, sand, and grime
 * A partially open crate
 * A cache of weapons that were bound in clusters with leather straps around them. Part of this cache were:
 * Four well-made longswords,
 * Four well-made short swords,
 * Two battleaxes
 * Two halberds
 * A locked, dark wood case, about four feet across and a foot wide, that was closed and latched,
 * When the latch was opened a blade fired out from where the lock was. Inside, there was a beautiful jewel-inlaid, curved pure gold color blade called Summer's Dance. that seemed to bend with movement before flicking back into place. It was well-balanced, and lighter than expected.
 * A foot and a half by a foot and a half flat locked iron box. With a simple iron look to it.
 * Inside there was a beautifully-smithed sword handle and hilt made from silver with an acorn-sized emerald set on each side of the hilt, right in the center. The blade extended for an inch before it's broken off at a jagged angle, which seemed to have broken off at some point.

The Rock Formation The oblong rock formation was about a six to ten foot at different places. It had a pool of water where mist was rising and sifting from it, which was loosely drifting off of the surface of the water. In the in the silt at the bottom of the water laid a smooth polished stone that looked like a cat's eye. It had a yellowish color to it and there were striations that refract light around it. At one end, there was pointed oval line carved in about three inches across. Around the edges of it, there were dozens of metallic objects with symbols of deities that were outlawed by the Empire of different shapes and configurations and designs. A number of those were scattered about, some in disrepair, with actual pieces of dried barley and other grains around it. There were symbols and worship idols from:
 * The Archeart,
 * The Changebringer, Avandra,
 * The Moonweaver, with the two crest moons across the silver cross,
 * The Wildmother, Melora, with the hook and the wreath,
 * The Stormlord, Kord.
 * The Everlight,
 * The Lord of the Hells, Asmodeus, that had a dark horned crown,
 * The Strife Emperor, Bane, the deity of conquest. With a series of chains and shackles that are across what looks to be almost a coffin-like box,
 * The Scaled Tyrant, Tiamat. With the clawed hand,
 * The Traveler.

The Small Pool
Beside the small entrance pool there were small mounds of various minerals that had long dripped from the ceiling from condensation and various water flows that have come through this interior cavern and built a hard, rocky platform that's emerging just outside of where the pool ends.
