 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 Athesias 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".

Athesias 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
Athesias is the cousin of Zhafe Uludan, the Marquis of Nicodranas. He was originally employed as a teacher at the Soltryce Academy. He was considered effective in that position, but he was felt difficult to trust with state secrets because of his narcissism and fondness for spectacle. As a result, he was promoted to Archmage of Diplomatic Union of the Cerberus Assembly as soon as the position became available.

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

Zeddan Graf
Athesias has a rivalry with Zeddan Graf, who performs a similar role for the crown and as such often runs into Athesias abroad. The two loathe each other, and Athesias enjoys ruining or undermining Graf's plans. Ludinus Da'leth remarked that, should Athesias decide to be present for the peace talks, it would be "interesting having to keep him and Zeddan civil".
