The headquarters of the Brotherhood of Guardians, Haven is located in the Forbidden Zone, a dimension split off from the rest of Mobius with its entrance disguised by a holographic wall of fire. Haven is the most advanced facility on Mobius, and all Guardians not on active duty reside here. Haven also serves as a monitor for nearly all activities on Angel Island, and many on the rest of Mobius. Haven was originally used as a training center by Steppenwolf, who was brought to the location by the fire ant Christopheles. During the Dark Legion Quantum Beam attack, Haven was demolished.
