Jour d'apothéose

Missing, extremely new, or very obvious to obtain.

Apotheosis is the glorification of a subject to divine levels and, commonly, the treatment of a human being, any other living thing, or an abstract idea in the likeness of a deity. It's used to describe when a mortal is elevated to divine status, often through great deeds or sacrifice. In the case of this chive, it refers to the Guard's unwavering faith in Talanton and his sacrifice to obtain information on Nikador to bring an end to the conflict.
