One way of getting here, The Concave, is through conflagration of your Soul. Not a nice way to arrive, but at least you'll have the benefit of a guide, unlike most others.
In a small inn (the more remote the better), a man turns up dead. There are no wounds on his body what-so-ever, and he aboslutely reeks of garlic.
The man died of a curse that forced him to eat a clove of garlic a day or suffer the penalty. This gets really interesting if the body somehow appears on top of a someone the villagers are suspcious of.
