Plot
Geralt is hired to kill an Allamorax which is deemed responsible for the deaths of several fishermen in Bremervoord. He lets the creature go after the merman Deroua beg to have mercy on it and claim that the Allamorax is not responsible. Since Geralt forfeited the kill and the prize money, Jaskier accepts an invite to play at the local festival to earn money.
There, they meet Jaskier's childhood friend and bard Essi 'Little Eye' Daven. King Usveldt and his son prince Agloval attend as well, along with the King Usvelt's bastard son/military advisor Zelest, who used to bully Jaskier when they were young. During the festival, a boat with pearl hunters is attacked. One of the fishermen makes it to the festival and before dying, says they were attacked by Vodnik (humanoid fish creatures) on the sirens' order. King Usveldt has originally refused to take action against the merpeople because his son is in love with the siren princess Sh'eenaz. However, this attack finally begets retaliation, with King Usveldt ordering Geralt to find and hunt the ones responsible for killing the pearl divers. Also during the festivities, Agloval is introduced to a young human princess named Nispen by his father.
