Kalen is the corrupt former governor of Raven's Roost.
Kalen's rule was put to an abrupt end by a rebellion led by Magnus Burnsides. Three months later, he returned to Raven's Roost, and, in retaliation for being deposed, bombed the support beams for the Craftsman Corridor. This attack ended up killing 76 people, two of those people being Julia Burnsides and Steven Waxmen, and caused people to evacuate Raven's Roost in fear of more attacks.
His current whereabouts are unknown.
