Morlock, alias Bergheim Chrome, sports light gray hair, a long gray beard, and brown eyes. Once a formidable sorcerer, his research into ancient magic two decades ago cursed him with severe dementia and chronic memory loss. This affliction triggers frequent forgetfulness—spell incantations, party loyalties, personal history—and chronic back pain. Despite this, he wields exceptional magical prowess exceeding level 80, unleashing potent spells during rare lucid intervals. His personality blends flirtatious charm toward women he meets with bursts of crude humor. After discovering Raelza living among wolves following her parents' death, he adopted her; she now acts as his minder, tempering his scatterbrained tendencies. Though often exasperated, Raelza deeply cares for him, reacting with distress during his near-death episodes. Morlock possesses an auto-revive ability, recovering after apparent demise. His past indirectly caused protagonist Saitou's dimensional transportation via a spell from his grimoire. Saitou later uncovered hidden spacetime magic within it, keeping it secret until needed. Morlock warns Saitou that returning to his original world would prove fatal due to temporal-spatial alignment with his near-fatal accident. In combat, his dementia renders him unpredictable—misfiring spells or forgetting objectives—yet momentary clarity makes him a high-level magical asset. He adventures partly because he forgets retiring. Beyond his party, dwarf mage Gibungle claims pre-curse mentorship as his former student.
