There's an experimental mind blast rod in it. A polearm that only psionice, monks and bishops can use, and that casts nuclear blast al level ~3.
It is possible, but not easy, to get it without aggravating the T'Rang, but IMO it isn't worth the effort.
You'd have to find some monsters nearby, and lure them to this room. The guards might 'retreat' and leave this spot, guarding their new area instead.
Then you can open the door. Enter combat mode, run in to grab the rod, and run out immediately. If you manage to leave the room (there are more T'Rang gurarding inside), combat ends.
