Giebe Haldenzel is the Giebe of the province of the same name and brother of Elvira.

With his dark green eyes and dark brown hair he shares a strong resamblence with his sister.

Spoiler from Part 4 Volume 4 Giebe Haldenzel has a forceful, yet friendly attitude. It isn't clear whether it's his natural charisma or intentional skill, but he is very good at manipulating people without them even realizing they are following his whims until they are already doing a task for him. And this isn't limited to inexperienced people, even the commander of Ehrenfest's Knight's Order Karstedt fell victim to this once, during a spring prayer visit to the province, where he ended up roped into an extensive feybeast hunt and only realizing partway through.
