For the four ways to enter Khalaan, this is the Unaffiliated one.
The player finds an out-of-the way book of or in the Imperial Archaeological Society which speaks of a hidden world and hints at a 16 bell piece melody that needs to be rung in order to access it and its hidden riches. The last entry should mention that the writer (who should write about feeling sweaty and sick prior to this) was about to venture to Roa Dyr.
Location: Small Zone #2 and Medium Zone #2 Daedric Doors in Medium Zone #2 to the Blood Ruin. This is a medium sized Daeric interior with some fantastical effects going on as this is an important building in the realm. Make use of blue lighting and particle FX. The exit from the Blood Ruin is in Small Zone #2. This is the room where the head honcho of the realm is found (Methats Uldun). He will not attack the player and there should be some dialogue (not necessarily part of this claim) to add character.
Location: Small Zone #1 and Medium Zone #2 Daedric Doors in Small Zone #1 and Medium Zone #2 that lead to the Desolation Tower. The tower has 3 interiors: "Desolation Tower", "The Whispering Hall", and "The Echelon Rooms" (which are only populated by different ranking Dremora).
Location: Medium Zone #1 Ancestral Tomb belonging to the Indoril family in the Manor of the Lords. Crumbled inside, small tomb. Skeletal Champions and Ghosts.
Take cues from the Raathim Ancestral Tomb in TR_Mainland. This one is considerably older than the Ancestral Tombs of today's Morrowind and should not use modern conventions. Consider using the Stronghold or OM set, or a mix of both.
Location: Medium Zone #1 Minor home, has a second room that leads to some caverns in the sewers (Claim #11).
Old Mournhold set. The family that lived here keeps up their daily lives as best as they can, but they understand less and less of how mortal life worked.
