Infestation: Great Mausoleum

#6: infestation
1) What brings the players to the tomb?
Friend or family member went down as part of a burial party and was killed
2) Who was buried there?
King’s daughter recently died and was to be buried. The “great Mausoleum” is said to hold the remains of the progenerator of the royal line, actually held …
3) What defenses does the tomb have?
The tomb’s borders are magically warded (sphere) to keep others out, and unknowingly to keep infestation in. the “great Mausoleum” has runes etched all along the outside. The stone golems who guard the interior are destroyed and half eaten.
4) What kinds of creatures live there now?
Prompt points to invading insectoid creatures from the plane of elemental earth. I am going to reskin umber hulk’s to fit this description. Making tiny (with 1 hp but nasty bite, come up out of floor and target metal armor), small (9) and medium (3) versions with lower strength accordingly, the large one was slain by whatever came out of the “great mausoleum”. Remove their gaze attack and give them a meld into stone ability as an action, make their natural armor same as stone skin. They will run away if injured 50% or see a larger one taken down.
5) What is the architecture like?
White marble and gothic grandeur recently covered in dust which has been disturbed by a lot of recent activity. All the royal family is laid to rest on raised daisies in salt coffins, aside from the “grand Mausoleum” which is constructed of white marble.
6) What condition is the tomb in?
The “Under Hunks” (umber hulks) eat stone and have really been enjoying the marble and salt as well as less extravagant coffins of marble and such of other prominent people buried here., so large chunks have been removed from everything and new tunnels have been gnawed out. May of the coffins have been eaten and the residents are unceremoniously revealed.
7) You do you!
Inside of the grand mausoleum is inscribed with infernal wards to keep an angel (fallen?) (progenerator of ruling family of aasimar) who was imprisoned there for unknown reason and who has also disappeared from the crypt.
