Letham (also Ledham) is the “King of Soma known in the multiverse,” a damned soul in Circle 4. He had “the drug of the gods.”
He was damned for avarice: his objects and purse were confiscated and taken to the City of Dis. Maristo recognized him. When he receives hope, his soul takes form and consistency.
He was a companion of Maristo, Ariel and others. At some point he was near “the anthropic escape,” possibly rehabilitated with Minborgen. A cross-gesta connection links him to an episode of Soma and drugs in the shared cosmos.
