Archibal Kelshanne
From Dreams of Hope
Archibal of the Primal Forest was the last archdruid of the Primal Forest of Tal Elamor. He sacrificed himself to imprison the aether plague until it could starve to death. It didn't; instead, it and he reached a detente of sorts. When Ad Elementis cleansed the corruption of the plague, the Firebird's manifestation brought rebirth to both of them, returning Archibal and the plague (later named Bianca Kelshanne) to life as infants. They were then adopted by Pyrrha Kelshanne and Eskel and raised as their own children in southern Auringon.
Post-Rebirth
A sturdy human infant, much more mentally and emotionally mature than most. He lacks most of the memories of his prior life...or maybe they're just suppressed.
