Intrepid explorer (in his younger years) and self-made entrepreneur Gimbo Tinkertorque has just landed a job that could finally allow him to pay off his debt to the eccentric and vicious Nexus Prince Kalil. With his crack crew of wayward mercenaries at his side and a juicy contract to slay a black dragon princeling firmly in hand, what could go wrong? For the Problem Solvers, it's rarely a question of if, but when. In a freak turn of events, one of their own is imprisoned in Blackrock Spire and a simple job becomes a race against time to deliver a friend and comrade from under the gavel of Blackrock Clan justice.
