Velkhana Known as the "Ice Dragons that Freezes All" or the "Iceborne Wyvern," few records of Velkhana exist.
As such, they remain shrouded in mystery. Their icy breath is so cold that it can form massive ice walls and spires out of nowhere, and it is even powerful enough to freeze other monsters.
Some reports indicate that Velkhana will freeze their rivals in order to establish their domain.

Risen Crimson Glow Valstrax Risen Crimson Glow Valstrax are elder dragons that have found a way to overcome their affliction.
Very few will be able to withstand their ferocious attacks.
