The Kindred was one of the gangs that The Brotherhood Janko teamed up with in order to take down The Gray Orb. They are led by an arcane caster named Vespus.
After the fight with the Gray Orb, Giovanni double crossed the Kindred (and the Fire Kings), and was nearly assassinated as a result. Later, the two gangs beseiged the Brotherhood at the Gray Orb manor. The Party helped Giovanni and The Brotherhood Janko to defeat them in exchange for a cut of his profits.
