Here's the ruin chanter. Apologies that the formatting is crap, the pdf looks pretty.

RUIN CHANTER

Source: 3.5E Monster Manual V.

A ruin chanter is the personification of worldly decay, guarding ancient ruins and forgotten outposts. A ruin chanter appears as an elfin figure garbed in ragged clothing with a tattered, rust-colored cloak. Weathered but clever-looking, ruin chanters almost always sing a mournful dirge that can sometimes be heard at surprising distances.

Guardian of Ruins: A ruin chanter is literally birthed by the ruin it claims as its territory. It will attempt to prevent a large population from returning to its ruin and absolutely oppose, with deadly force, any attempt to build permanent structures or rebuild any part of the ruin. If the ruin it dwells in were to be rebuilt, the ruin chanter knows it could no longer exist.

Lore of Ruin: A ruin chanter knows an amazing amount of information about the ruin it haunts. Sometimes a ruin chanter can be bribed or persuaded into sharing some of its lore, although it is unlikely to favor would-be explorers with any information that would encourage them to delve within its territory.

UNGULOSIN

Source 2e Planescape Monstrous Compendium Appendix III

In the early days of the world, the seas and lands were threatened with constant destruction and re-creation as great powers warred over existence. Slowly, primal spirits awoke to defend the nascent world. Some of these spirits manifested directly, taking physical form in order to enforce a balance between the primordial forces and those of the gods. Others acted through natural processes and the powers of the world itself. Almost all of them remained on the world to defend it, but a small force of spirits chose a different path. This force split into two groups. One went to the Astral Sea while the other traveled into the Elemental Chaos, seeking to negotiate a peace.

The group that entered the Elemental Chaos found itself engaging in protracted negotiations with primordial powers of water. For eons they argued and debated terms while the battle for the world raged and quieted. As it finally died down, the spirits and primordials struck a bargain and fused into ungulosin, agreeing to guard against divine intrusions into either the natural world or the Elemental Chaos. Now ungulosin dwell in the greatest and deepest bodies of water in the world, including great lakes, oceans and underground seas.

Lost Brethren: The fate of the spirits that journeyed into the Astral Sea is unknown, but it is possible that they have become something akin to the ungulosin, joining with angels or other divine agents. The ungulosin would dearly love to determine the fate of their lost brethren, even if that fate now makes them the ungulosins' enemies.

A Swarm of Aquatic Life: Each ungulosin appears to be a swirling mass of water and eels, fish, sharks, starfish, crabs, seals, octopi and whatever other life dwells in the body of water it dwells within. Even if it is damaged, more life constantly joins the swarm, allowing it to regenerate.

Against the Gods: Ungulosin manifest to defend their waters against divine intrusion, whether direct or indirect. If the gods send agents into a body of water in which an ungulosin dwells, especially powerful ones such as angels, the ungulosin may manifest to drive them away. Likewise, if the worship of a sea god becomes too prevalent around the ungulosin's waters, it may rise up to destroy seaside temples of that god and wreck ships casting religious sacrifices into the waves.

Next up, obviously, is the scyllan, from Stormwrack. Some of the flavor text for it will not work too well for most campaigns, since it mentions the politics and rulers and stuff has happened that shifted that all around a bit in the past in my campaign (e.g. Asmodeus is dead, there is a distinctly different history of the Hells, etc). I have run with the idea that Scylla was an ancient arch-devil.

SCYLLA

Source: 3e Stormwrack (the scyllan).

Over the eons, the Nine Hells have been ruled by a variety of arch-devils. Lucifer predated and then succeeded Asmodeus; Geryon fell; tales of the struggle between Tiamat and Bel for dominance over Avernus could fill volumes. Other, more ancient devils have ruled one Hell or another as well, Scylla among them.

So long ago that almost all references to him it been lost, Scylla ruled Stygia from the frozen depths. Now it lurks in the Underdepths, the deepest reaches of the sea where light never reaches, brooding in the frigid waters of its exile. Scylla rarely stirs, but sometimes vomits forth a clutch of eggs that hatches after a century into a batch of scyllans.

Devil Men of the Deep Cultists: The devil-worshiping sahuagin typically devote themselves to Sekolah, the Great Shark, but there are rare instances of small groups, cut off from their normal religious heirarchy, who have fallen into a crude form of veneration of Scylla. Such groups do not consort with sharks, and are usually the remains of lost raiding parties that failed and were driven into unknown waters. Perhaps it requires a deep and bitter sense of failure to achieve communion with Scylla after so many eons of brooding.

Weird Broods: Scylla vomits forth the eggs that become the scyllans. Scyllans are less successful at reproducing, creating strange broods of mutant fish with tentacles or pincers, or even more bizarre stillbirths so disturbing that they make scholars shudder. Few offspring of the scyllans are viable, but a few escape to the open sea, where their true source is rarely determined.

Strange Keening: Scyllans make a dreadful keening noise that can be heard miles away on the open sea. The sound is frightening and malevolent-sounding, and most fishermen and boaters lay in a course for shore as soon as they hear it. Those foolish enough to seek out a scyllan have an easy time following the noise, but usually a far harder time surviving the encounter.

Obsessed with Failure: Scylla broods for eons on its failures, wallowing in bitterness. The few cultists that follow it do so only after suffering great failures themselves. Scyllans are prone to overestimating their ability to carry out complex plans and failing to bring them to completion. When a setback occurs to Scylla or one of the creatures related to it, that creature obsesses over the setback, turning even a minor defeat into the end of the world. Scylla and its offspring and followers hold grudges forever.
