Hadarach Mistwroth's Doomsday Bunker

Clan Mistbreath is notorious in their paranoia and misanthropy, at least when compared to the other clans. They keep to themselves, and they stay in their mountains, and they build elaborate holding places for their various schemes on how to survive the coming apocalypse.
One such person was Hadarach Mistwroth. His vault was noted for how carefully he locked it. In fact, he locked it so well that he was unable to open it again to put in any supplies, so when the dragon came he was caught out. Naturally there were any number of folks who thought he'd left immeasurable treasure inside and so devoted their lives to getting inside. Eventually they managed it, but they were of course very disappointed at the results initially.
Now, however, the bunker is a kind of test for young Mistbreath folks, to see how well they do at breaking and entering.
