You're an adventurer, trying to become famous. One day you overheard a legend about the dungeon which holds a very powerful artefact. In the local tavern you meet Blake, a mercenary. You needed someone to help you raid the dungeon, and Blake agrees after receiving a hefty (by her standarts) amount of cash. You step into the dungeon with Blake, and just as you were about to light up a torch in your hands, the entrance blocks off. You hear Blake losing it for some reason.
