Is it just me, or is Estovion Lozarov from Broken Moon based on Ben Linus from Lost. The case:
* He is a Machiavellian manipulator of a remote lodge/"island" surrounded by danger.
* He can summon an evil spirit, a "monster" to enforce his rule.
* He is the wrong side of middle age, bookish, somewhat weasely looking, has problems with his eyes, but is somewhat spry despite all of this.
* He has grew up in the lodge/"island" and it is the only home he has ever known.
* His father was a caretaker of the lodge.
* He plays politics with the mainland, despite his remote location.
* When a child, he investigated a forgotten temple and uncovered an ancient spirit. He also made contact with an evil faction and forged an alliance.
* He is an amoral liar.
* His favourite spell is Evard's Black Tentacles.
That's not all. In the same adventure there's a place called Chastel. Jean Chastel was the supposed killer of the Beast of Gévaudan, a legendary monster which in truth PROBABLY was a wolf, of a bunch of wolves... Legends claim it was a werewolf, or some other monster...
