Ursus is one of the five Unions the player can join in Unchained X. The animal representing the Union is a bear.
The Ursus Foreteller is Aced, a man who wears brown robes with a cream hood and a bear mask hiding his face. His Keyblade is brown and gray, with a rock motif.
Ursus is the smallest Union on the Japanese version of Unchained X.
Both Aced and Gula have dark borders on their robes and hoods.
Aced's name derives from the latin word "acedia", which means to represent the sin of sloth.
