📋 About This Mod
Explore an abandoned fort deep beneath the surface of Morrowind, and then go deeper. To the twisting warrens of the rats, and the rot below. Or two a new miniature plane of oblivion, the domain of Nikiki-Kon, the Mazken who defied
Deep Seileam:
The imperials had made a discovery, the mages guild was summoned, a secret fort constructed.
But greater webs were weaving, an ambitious daedra against the Madgod scheming
Deep below the the surface, and unto realms unmapped, domain of the self proclaimed goddess
Into this new nightmare fleeing, unprepared, unaware, forever dreaming
A new adventure with over 40 hand crafted cells ranging from abandoned forts to Seduction, a new (miniature) plane of oblivion and many things in between.

Starting This Mod:
Travel to Seyda Neen and then take the path left out of the city towards where tarhiel (the mage who falls from the sky) dies in the base game. Here, take a right into the forest and nestled up against the cliffs will be a pile of rocks with a dark cave you can crawl into.
Recommended level (single player) is somewhere between 14-18, the hardest areas would have creatures that are on the level of Golden Saints. Best to be with friends or moderately strong for final areas.
Compatibility:
This only edits a tiny part of a cell near seyda neen (This change has been tested with a ton of different mods that improve the surrounding area so unless you have a mod making drastic landscape changes this shouldn’t conflict with anything). All other content is new cells.
This was developed and tested on OpenMW and Tes3Mp.
Efforts have been made to allow it to be playable on vanilla/mwse but this is untested
No other mod conflicts known.
Multiplayer:
I tried to balance this mod with some multiplayer in mind, additionally there are a few optional areas that are in theory only accessible if playing in multiplayer (clever
