Adellion was an in-development fantasy MMO set on the island Aryiure in the Adellonic year 3200 TS, a land with Medieval-like technology and inhabited by six different races, each with history with the others as well as the land itself. The game had a sense of realism and featured both perma death and lack of magic. Adellion aimed to be non-linear, and player-driven. Roleplay was heavily encouraged and even required. Advancement was skill-based, and gameplay featured some simulation type elements, including weather systems and day/night shifts.
