Card Lores:Arctic Zonekeeper, Blue Balien

After countless fights against intruders from Cray, Winter Reefs were attacked by an mysterious enemy. It had no shape & knows only to consume. In the current days, people of Cray refer it as "Void". It seeks Winter Reef's miraculous power of healing, consuming many guardians on its way. In a fight, Void injured Balien in a fight, damaging his ancient armor.

To halt Void in its steps, Mother Reefs used a portion of her power to keep Void at bay, sealing away Winter Reefs & Crystal Reefs in the process. In the meantime, Balien was nursed back to health by the sister of his mother (Mother Reef), Undinale while an elder of the Marina repair his armor.

Now, in the present times, Crystal Reefs returned. Donning his new armor, Balien & his brethren walked out to the new world.
