Yaldrinyss Dihasco

This is a man the Iron Maidens met in The Guardian, the lone mountain that guards the portal to the Shadowfell. He travels with them into the Shadowfell to stop Unfreth Daero from absorbing the gatestone and opening the portal permanently.

Really a Bronze Dragon in human form. Very few know of his true nature, and he has guarded the gate in some form or another since he participated in the raising of the Guardian to hide the entrance to the Shadowfell.
