Like other Seck, the mage is a grey-skinned, muscular humanoid. He wears a finely-wrought cape and body suit. The mages wield Seck Staves but favor the Flame Blades spell in combat.
The Seck race is referenced (without being named) in many cutscenes during the Ehb storyline (the Seck Resurgence), always as an "ancient evil": to wit, the Seck Mage is much bigger and tougher than a hero character of his level, and in groups, the Seck pose a dire threat to the party. Magi are encountered in Castle Ehb and the Vault of Eternity.
