The Creature Arena may be the least updated place in fantage and one of the least populated places.If you enter it, even on a full server, it is likely that no one will be there. It seems in recent years, Fantagians have not been interested in buying creatures.
The Creature Arena portal was moved to the Forest after the Fantage update in 2014.
