My Players finally reached the "Traveling Mausoleum" the Mobile Fortress in Shadowfell. The Living are not welcome inside as it is a home to many undead dangers, with the Skull Lord ruler being their main target.
(I really liked the idea of the Walking Mausoleum in Elden Ring, not gonna hide).
This one is complex of buildings, mostly ruined and clouded with life sucking fog. The tendril like legs, (which are, fun fact: made of mixture of entangled bones and flesh), tend to bury themself in earth, when the fortress is not moving.
I'm very excited for the next few session of dungeon crawling!
It is been a while since I did some enviro, I hope you like it!
