Dragon's Crown

The Kingdom of Hydeland possesses vast labyrinths and catacombs beneath its civilization, fantastical monsters in the darkest and most desolate forests. and the legendary relic, the Dragon's Crown. A mysterious coven of magic-users with influence in even the highest levels of government seek the treasure and have used their sorcery to link together long forgotten ruins, dangerous labyrinths and many other areas together in order to search for it. But there's one group that wants to retrieve it before those who would use it for their own sinister purpose do.
