As the Pre-League of the Prime League is ongoing, new changes are coming to Norheim. The keyword to the 2.1 patch is "polishing". The Training Camp will provide unlimited opportunities to polish your Immortal units and strategies.
The Illusion Battlefield was previously a mystical land where two Alliances would fight each other for the great treasures of Hornheim. With Patch 2.0, however, the Illusion Battlefield will become the staging grounds for the Prime League, in which Alliances will battle for the title of Supreme Alliance.
