Aiden hadn't stepped out of the temple premises in a long time. After Lord Kieran's death, he voluntarily resigned from his position as the Grand Master of the Aisgarth's Frost Guards. He also didn't acknowledge Killian Fleurnoir as the new Night King, so there was no need for him to protect the seals that kept the ancient demons in their prisons.
It had been two years since Lord Kieran's death and Iris's transformation as a demon. Aiden regretted not being able to save Iris from danger. He knew his high lord would want him to stay by her side to protect her, but Aiden would rather be here than anywhere else. However, it didn't mean he wasn't in touch with his family, who was currently keeping Ren Scarborough safe from the Red King's scheme.
