|Heroes:|| Dragon Knight|
Byssrak is the Void Eldwurm. He is extremely brief with his speech, only speaking with one word at a time and does not use any sentences or phrases when speaking. It is from his species that Kaden's Blade was forged with, using the remains of an adult void dragon.  Concept art reveals that he has wings much like the rest of his thunder, but they manifest in the form of energy rather than a physical appendage of his body.

The eldwurms are a BIG DEAL in the new lore of #DOTADragonsBlood."

Maybe the least easy (also it’s nearly impossible to find one). And he did it WITHOUT that sword so… yeah. Bad ass."
