Abyss: Kraken

Smugglers Guild settled in the heart of the giant sea creatures cemetery, in the darkest depths of the Deep kingdom. In this disconcerting necropolis, with the help of mysterious Krakkens, representatives of Guilds are trading NEBULISES. Nebulises, wonderful black pearls, are the unofficial currency of the realm.
