The Colosseum
From Starsonata Wiki
Like its namesake, The Colosseum is an area of ferocious battles, heroic victories and depressing losses. One of the three orbiting wormholes in the Arena Lobby, high-leveled players come here to spar, duel, and fight all-out. Not a place for the faint of heart! Arena Items drop here.
In this galaxy, items do not pop out of ships, gear glue is not used up, and players are not automatically marked as enemy for aggressive actions against other players.
