|Wikipedia||Antigonus I Monophthalmus|
Antigonos is very recognizable due to his eye patch. He also has a rather strong build and black hair with a beard. His long clothes indicate he is not of poor standing.
Antigonos first appears in Chapter 3: Hometown Kardia (2), when he and his two companions come running to Kardia's gates to join Eumenes and the old lady, who are trying to get in the city. Antigonos there explains Eumenes that he is a merchant from Perinthos who is visiting an old friend.
When the group finally gets in Kardia and they part ways with the old lady, Antigonos asks Eumenes to take him to the house of Hieronymus.
