During the post-Blood Omen era, when Kain explored Meridian's Lower City in search of Sanctuary, he could approach the exterior of the local Playhouse and overhear two nearby peasants – one a male patron of the arts, discussing "imagery mixed with impressionistic neo-modernism" with his bored female companion. Presumably referring to a play they had just seen, the man commented on how the pathos of the protagonist reminded him of "Sergio's use of deus ex machina in order to resolve dilemmas of the ego". The woman simply protested that she was hungry, obstructing any further intellectualism.[BO2-C3][BO2-Misc]
Judging from the context of the man's description, it could be construed that Sergio may have been a famous Nosgoth storyteller, playwright, or artisan of some kind.
The man's description of the pathos of the protagonist – "the way he couldn't decide whether to allow fate to sweep him forward, or if he should thwart destiny’s cruel hand" – is noticeably reminiscent of Kain's opening monologue in Legacy of Kain: Defiance.[DEF-C1]
The environment surrounding the Playhouse includes what may be advertisements for plays named "Avenging Angels" and "The Village of the Insane". It is possible that one of these is the medium being compared to Sergio's work.[BO2-C3]
