Knight Odo was a member of the royal entourage of Meve, queen of Lyria and Rivia during the Second Nilfgaard War. After the Battle for the Bridge on the Yaruga he introduced Geralt to his queen because she wanted to knight the man who had defended the bridge against the Morteisen Battle Group and led the Lyrians against the Nilfgaardians. Meve had sustained a rather serious facial injury during the fight and had lost several teeth. Hence she could not recite the accolade formula. Odo did that in the name of the queen, but the knightship was given to Geralt from queen Meve. Geralt was now granted the right to call himself Geralt of Rivia.
|“||'Her Royal Highness Meve, Queen of Lyria and Rivia,' said a knight in a purple cloak decorated with gold embroidery, standing beside the woman, 'is asking if you led the heroic defence of the bridge on the Yaruga.'||”|
