AdventureQuest Worlds/Guardian tower

The home of the warriors in Battleon, Guardians, which first appeared in AdventureQuest, made their way into Dragonfable, Mechquest and finally AdventureQuest Worlds. They wield Guardian Blades, and the Guardian Tower Houses a few guardians. (When you go there you can see them.) It is also where The Guardian, DragonLord and Star Captain shops are.
