Halicarnassus was a million base inhabited by Crimson, Shortbus Caliphate, and Astral Brotherhood members for its almost year long lifespan, although it existed independently of these groups. Halicarnassus was founded by a short-lived group of trusted Crimson and Shortbus Caliphate members (called Stashcrew) on December 21st, 2020. It served as a both a place to deposit the stashes several members of the group had found, and to provide a longer-term base for the members of the group.
