Yupe, only when the guild leader summons them. We might add something for a work around that at a later time but for right now; only a guild leader can recall you into there. it has a PvP room, disguise NPC, buffer, broadcaster, etc. There is also a NPC in Forsaken City that allows the owner of the pass (NOT the guild leader) to warp their entire guild right outside the Castle (does not waste an e-call) this allows for tactical insertions without the guild leader leaving his guild and giving them orders prior to the being recalled.
