With thick plates of black armour all over his body, covered in spines and horn, Rhavana was almost as large as Kalessaros the Black at just short of a kilometre long and with a 2900m wingspan.
Rhavana was known as extremely ruthless, determined, and sometimes a little stubborn. He considered himself one of the most powerful of Great Dragons, below only Kalessaros himself, although whether this was true or not is a matter of debate.
Rhavana was physically an extremely dangerous opponent. He was also very adept at magic, and known for his lava-related spells.
