Citadel Sealt

Citadel Sealt stands as one of the Doomguard's four negative quasielemental headquarters, dug out of a single massive salt crystal in the Crystal Range of the plane of Salt, directly adjacent to the Negative Energy Plane. This citadel is led by Doomlord Roth, one of the faction's accelerationist sect, seeking to speed the rise of entropy in the universe.

Of all the negative quasielemental planes, Salt is perhaps the safest; as such, it perhaps isn't surprising that most of the work the Doomguard wish to keep out of the public eye is performed here. While occasionally the other three headquarters do host business of one sort or another, the ease of both traveling through and surviving on Salt means that all else being equal, Citadel Sealt is the first choice. As a result, Doomlord Roth, the citadel's overseer, has gained a certain amount of prestige in the faction; it was at his urging, for example, that the faction first pursued its research into the development of the entropes. It's further led, however, to Citadel Sealt being the most well-protected of the four Doomguard citadels. While each of the others has had their trouble with espionage actions now and then, not once has an outsider been caught infiltrating Citadel Sealt.
