Great Beast Albion「アルビオン Arubion」 are giant golems created by the Demon Clan during the ancient war between the allied clans. They were reawakened after the seal on the Coffin of Eternal Darkness was broken.
Albion are gigantic creatures the size of mountains. They appear to be formed from the earth by demonic magic and as a result possess the black marks that are typical of the Demon Clan.

The Albion were created 3000 years ago by the Demon Clan as weapons to combat the allied clans.
