Hades Temple
The not-so-humble abode of the Lord of the Dead. It's one of the few places that don't change location, the layout however… well who doesn't get bored of looking at the same walls all the time? If you'd like an audience with Hades this would be where you'd come to try, of course whether he's there or even willing to listen to you is always debatable. Maybe you should try when his wife's around, rumor has it he's in a better mood then.
While the gates of Hades' Hall do not change, the interior tends to change, seemingly at random.
Now that Hades is dead, the Hall is open for anyone to venture into. It seems the Hall has been abandoned, at least for now...
