Umbra Hold


Umbra Hold
This massive, sprawling necropolis is hidden underneath the waters of the Dead Loch, protected against flooding via a massive arcane bubble. Although the denizens of the city are all dead or undead, the city itself seems alive. Like some sort of leviathan-esque machine, the city’s structure constantly shifts, revealing new areas and closing others.

Umbra Hold can only be entered & exited via the Ferry Man stationed at the docks adjacent to the Silver Citadel in Penumbra. The Ferry Man is a seemingly friendly Merrenoloth and will take anyone into Umbra Hold via his magical transporting raft. The Ferry Man always takes people to the City Square in Umbra Hold. The Ferry Man is immune to all effects and damage.

The only way to leave is to travel back to the City Square to find the Ferry Man who always waits there, immune to all effects & damage. The Ferry Man will return you to the docks adjacent to the Silver Citadel in Penumbra. The City Square must be cleared or the Ferry Man won’t let you leave.

Start in City Square. From there, you can either Explore The City or go to any District. Buildings in Explore The City either lead to the next random building or immediately back to City Square. Any District leads back to the City Square.

You cannot go back to a cleared building in Explore The City, it is always a random new one. You cannot go to any District from Explore The City, you must return to the City Square. You cannot go from one District to another, you must return to the City Square first to go to another.

Curses or other similar effects placed on you in the dungeon not done by a creature are suspended whenever you leave these player lands, but return upon reentry to these player lands and continue their duration from when they were paused.

Enemies can, and will, leave their rooms & follow you to the next unless otherwise stated or obstructed.

Room Height – If not stated, assume 20ft. If no roof, traveling into the air more than 100ft magically teleports you back to the ground unless otherwise stated.

Once a dungeon room is cleared, it remains so until the next visit to Umbra Hold or unless otherwise stated.

You cannot navigate the dungeon in any other way besides the intended paths, unless otherwise stated.

Teleporting within the dungeon from within the dungeon can only be done within the area you are in, i.e. within the same District, city exploration building, or City Square, unless otherwise stated. Attempting to break this lands the player characters teleporting in City Square with and immediately activates the Scaled Encounter. The other party members may choose to be teleported to City Square with them.

Lighting is always Dim Light unless otherwise stated.


City Square

This wide plaza seems to be an unmoving cog in this leviathan machine. In the center of this area in a strange magical device that contains a black crystal. The city around appears to be undulating. From here, you can go to any District or Explore The City.

– A DC 20 Arcana Check reveals the crystal to be an Arc Well.
