Sirrush Yvri is a golden greatwyrm and the most powerful metallic greatwyrm out of the five. He is a massive golden dragon that has two sets of long tendral-like whiskers that droop down from his snout. His wings are webbed all the way down his body to his tail. He has an elderly looking posture to him and speaks in a slow yet firm voice.

Sirrush lives in the floating islands of Mystara and home of the Aaracakora. The islands use to be one gargantuan floating island but where separated when Sirrush and his sister had a “heated” dispute. Now the islands are home to all manner or birds and young members of Sirrush’s family.
