In your ascension, you have absorbed the powers of the White Dragon Emperor Albion Gwiber inside your gauntlet and became the new White Dragon Emperor. You inherit all of his powers including Divide, Reflect, Reduce and various other abilities in his prime, and can use them without the limits placed by the sacred gear. However, do keep your arrogance in check, even the original White Dragon Emperor was sealed in a sacred gear.
(Your power is at around planetary level. With proper training, divide and all other power have potential to reach conceptual level.)
