Iridium doesn't recall his past travels, only that he has many of them and retains the skills in healing he learned on them.

He wandered for many moons throughout the lands, gathering knowledge and spreading wisdom of the forests from his youth. After much time, he settled in his current clan, where he plans to stay as the healer for the clan. He has offered many a time to try fixing Alaina's ailment but she insists she has come to peace with it.

He tries to get along with all willing to get along with him but finds Cinnamon kindest to him. Even if he can't remember why, he still loves her and her company and will remain loyal to her as long as he lives. In mornings, the Ridgeback is often seen using her extra 10 meters to cool around the far smaller Tundra until only his head is visible or perhaps a stray wing. Even then his nose is always pressed to her scales and hers, buried in his thick fur.

He teaches his arts of healing to Arcadia and often forgets to give her lessons but is starting to remember her more and more due to her scent.

Iridium is a benevolent creature who enjoys the company of his fellow dragons.
