Thegis

Thegis (ジーギス) was the test proctor for the Kingdom of Blumund's Free Guild branch.

Appearance
Thegis is a middle-aged man with dark hair and rough facial features. He used to wear a peg leg before meeting Rimuru.

Personality
Thegis is generally sarcastic and gruff in his interactions with others, only showing a humble attitude with his superiors and those he respects. He is very critical and looks down on adventurers who's fame overshadows their actual skill, viewing them as frauds. It's possible this attitude may stem from his bitterness over being forced to retire.

Background
Thegis was originally an adventurer in the combat division, but was forced to retire from direct combat after losing his leg. He became a staff-member for the Blumund branch of the guild, overseeing the promotion tests for combat division adventurers by making full use of his abilities as a summoner. He eventually regained full use of his leg after receiving a full potion from Rimuru, allowing him the option to once again continue his adventurer activities.

Trivia

 * Thegis is one of the few characters whose appearance was completely omitted from the anime as Rimuru's trip to Blumund with Eren's party was skipped.
