Athesias Uludan

 is a human mage and a member of the Cerberus Assembly, filling the role of Archmage of Diplomatic Union. As an NPC, is played by Matthew Mercer.

Appearance
Lord Athesius Uludan is a human male with slightly long salt and pepper hair that curls slightly and is pushed to one side. He wears a long black robe with silver and blue detailing on it. He appears very much a mage who wants to put together a good impression socially.

Personality
Yussa Errenis described him as "a buffoon".

Athesius is the member of the Cerberus Assembly who acts as their ambassador to foreign powers and interests, and also within the Empire when a situation requires some smoothing over. He wears a half-cocked grin and is very much a practiced, very smooth, tailored persona to social, charismatic, and persuasive interactions.

Background
Athesius is the cousin of Zhafe Uludan, the Marquis of Nicodranas.

Athesius was originally one of the most effective instructors at the Soltryce Academy, but his penchant for spectacle and his rampant narcissism made him a difficult ally to trust with state secrets. When the office of Diplomatic Union opened with the Cerberus Assembly, Athesius was quickly and quietly reassigned.

Athesius Uludan was present on the Cerberus Assembly ship the Wind of Aeons along with Ludinus Da'leth when the Mighty Nein arrived in Nicodranas just prior to departing for the peace negotiations with the Kryn Dynasty.
