> fire Thermolightcannon at unholy zealot
You fire the thermolightcannon, blasting the Unholy Zealot into oblivion and (amazingly) killing the Ur-Grue at the same time. For some reason, the grues in the room all die after the Ur-Grue is killed, leaving only a few of your allies alive. Congrats on killing the Ur-Grue again; not many even can kill it once.
> check ur-grue's corpse
You examine the ur-grue's corpse and discover nothing. However, you now notice a strange portal in front of you.
