The dwarf has been here for several hours! The door on the first floor is barred from the inside. He thinks the demons and cultists that they can see now are nearly all of the hostiles present in the tower. There's at least one more in the basement, "some sort of young fool," and he's also overheard references to the curator being alive and somewhere in the basement; he believes someone in the demonic forces has ordered the curator to be kept alive, and the other demons have, improbably, listened. This location is something of a secondary base compared to the Gray Garrison, and various additional cultists have been cycling in and out all day, sometimes for strategic discussions but other time just to drop off looted relics. Several of the Deskarans have made reference to a "Lord Xanthir," but thus far no one by that name has shown their face.
The cultists here have been planning for an assault on the Defender's Heart tavern; from what he's overheard, he believes that they have some form of exotic magical item crafter crafting single-use magic items capable of igniting wooden structures when thrown, more efficiently than ordinary spells, and bypassing some of the standard counters to brimoraks. It is possible there will also be brimoraks. (There are not currently any brimoraks present.)
He has been entertaining himself by coming up with impractical plans that could theoretically allow him to solo everyone here; although none of them were actually feasible, he does think those fallen columns could potentially be shoved in the direction of the cultists, or that loose rubble over there could be displaced to fall on top of them, or the other side of the locked door could be rigged to have a large number Explosive Runes displayed on the other side. It hadn't specifically occurred to him to plan for wings, but he feels like it must surely be possible to do something badass with them.
