The name "Arcania" comes from the latin word Arcan and means Hidden.
Arcania is the first server that Morgaroth appeared on Aug 7th, 2006. It wasn't killed because of a debug to players. Morgaroth was finally slayed after 2 years on Aug 18th, 2008.
Arcania is the world where probably the biggest scam in Tibia was done. Player Bedurion stole over 20.000.000 gp from people who decided to join his PoI quest service. However after it he became hunted by his former guild (Dark Purples Faster Turtles).
