Pelias

Pelias was steward of Apollodorus' Estate.

At some point, Pelias sent Ruia, a young worker to retreive a letter from the Pigeon Tower. After she failed to return, he sent Bayek to investigate and retrieve the letter. Bayek discovered Ruia's body in a nearby haystack, bringing her back to Pelias. From her body, Bayek discovered the letter and a badge which Pelias identified as belonging to Dymnos, the Master of Arms.
