Prokion Shrine is an ancient temple located along the eastern side of Dratan. While Juno's Velpist Temple is the temple of light, Dratan's Prokion Shrine is the temple of darkness. It was dedicated long ago to Eres and the worship of his darker magics. But just as the Velpist Temple fell into ruin after the war, so also did Prokion Shrine. The reason for this fall is unknown; all who could know have long since died--or been killed to hide the secret, perhaps. Prokion Shrine is now a den of monsters.
This is a very dangerous place hiding many ancient secrets. Scholars are fascinated by it and will often risk their lives or pay an adventurer to risk theirs for the sake of doing research here.
