Ga'al-Xox is one of the oldest Ga'al that were born due to the cooling of Karamja Volcano. He is sent with the player to the Elder Kiln to run an experiment for TzHaar-Mej-Jeh, which aimed to give Ga'al the memories of other deceased TzHaar from the past. It is hinted that if he were born successfully, he would have become a TzHaar-Xil, as he masters using a Toktz-xil-ul very quickly when it is presented to him by the player.
Towards the end of the quest, Ga'al-Xox becomes infused with the memories of TzHaar-Ket-Yit'tal, the late champion of the Fight Pits, and it is discovered that TzHaar are still aware when they have been turned into Tokkul. He also explains that the experience is horribly painful. He insists that TzHaar-Mej-Jeh and TzHaar-Mej-Ak do not continue with their idea of having Ga'al bound to the memories of previous TzHaar. When they make it clear they will continue with it, he claims that he is done with the TzHaar society. During a cutscene at the end of the quest, it is shown that he returns to TokHaar-Hok, the TokHaar who greets the player and allows them to attempt to fuse Ga'al-Xox with the memories of the deceased Fight Pits champion.
