Only BloodSpirals know where to find the entrance to their clan hidden in New York. The entire place is made out of dark stone, lit only by torches. A practice room is located here, as well as a secret exit used to fly out on Titans. Somewhere deep inside the corridors of this cavern like place is where Rassimov, the BloodSpiral clan leader, resides. Only the top clan members know where his office is.
