White dragon using his frost breath
A white dragon is a rare subspecies of dragon, apparently found in the Far North.[1] The average specimen is 10 meters long and can breathe a wave of terrifying frost which freezes everything within a range of dozen or so meters.[2]
To the inhabitants of the Northern Kingdoms, they are only known from tales of several fearless adventurers, who describe their scales as light gray to bluish white.[3]
