Recently a strange cave appeared on Amnish border. Only few of initial groups appeared when they were tasked to scout the object and they named it Hanor's Labyrinth, after a spellcaster who supposedly created it all to test his powers to the limit and to protect his vaults. One of the most intriguing things is the initial lobby, which is the key to everything. Every wall holds more than thousand stone tiles with engraved pictures. Some are glowing red, some are blue and some are unlit. According to those first adventurers, these act as portals to other parts of Labyrinth. But were few "monster leaks" recently. So the authorities decided to hire few experienced mercenary groups to empty out the vast dungeon.
