Bishop the Scorned spawns inside the ship (top level of the inside of the ship). His PHs are any of the pirates with "scorned" in their names.
He hits for a max ~14,000. Be warned that aggro can be odd in this area of the zone, leading to much larger mob assist ranges than normal (and awkward pathing which may cause a train).
