Aki of Clan Brokvar was the son of Jarl Udalryk of Spikeroog, and of one of Udalryk's concubines. Aki was named after his uncle, who died during a boat trip with Udalryk some time prior to the start of The Witcher 3: Wild Hunt.
Geralt and Cerys attempted to free Udalryk from the hym that possessed him. They did this by first trying to trick the hym into leaving. Cerys ran up to Udalryk's dilapidated manor which overlooks Svorlag with Aki in hand, and handed him to Geralt while telling Geralt to put the baby in the oven. Faced with this harrowing choice, Geralt may either put Aki in the oven, or hand him to Udalryk who runs into the house shortly after Cerys with a group of guards in tow.
If Geralt decided to put Aki in the oven, he engaged in a fight with Udalryk's guards, after which Cerys emerged from the neighboring room with Aki safe and unharmed.
If Geralt returned Aki to Udalryk, Udalryk handed the baby to one of his guards, and proceeded to punch Geralt in the face. The jarl and his guards then exited the building. Cerys explained the plan she had in mind, which would have involved taking Aki immediately out of the oven via a back panel that could be accessed from the other room. Geralt was then forced to deal with the hym "the witcher's way" by surviving a night in the hym's lair with Udalryk.
