The Hostile Hostel was the first building that THE Greytooth built. However, when he named it, he was trying to make a pun of Arms like weapons and the typical inn naming convention of "Arms of Whatever", but didn't translate it correctly. So the Hostile Hostel was born, which was also a pun, but one of a very different vibe. While it is one of the few large buildings, and the only one with temporary housing, it almost always has vacancies.
