Theo Lachesil

Theo is the Magic Caster Guildmaster of the Adventurer Guild in E-Rantel. He is an extremely thin and neurotic-looking man wearing a robe. Though he appears as a calm and wise man, his demeanor only hides a thirst for knowledge and all things magic that border on obsession. He is Lizzie Bareare's colleague in the study of the magical arts. He meets with the mythril-ranked adventurer teams of E-Rantel: Kralgra, Sky Wolf, Rainbow, and Darkness, along with E-Rantel's mayor Panasolei Gruze Day Rettenmaier and Adventurer Guildmaster Pluton Ainzach to discuss the appearance of the powerful vampire Honyopenyoko. Though usually calm, his composure was momentarily shattered with the appearance of a Sealing Crystal holding a spell of the mythical 8th tier that is considered to be a spell of myths and legends. Having lost his sense of self and overwhelmed with excitement, he went as far as licking it all over, then rubbing it against his cheek before being brought back to reason. (Source: Overlord Wikia)
