- Were you looking for the original lore version, who became Thrall?
Go'el is born right after his mother, Draka emerges in Azeroth. However, possibly as a side-effect of passing through the portal, he appears stillborn; Gul'dan, who assisted Draka in the birth, cannot allow the first orc born in this new world to die when he notices a nearby deer. Using the Fel, he leeches the deer of its life energy and infuses it into the infant's body, bringing him back to life (and changing his skin green) before presenting the child to the war band as "A new warrior for the Horde!"
Go'el is held by his father Durotan later that night, reminding him what he is fighting for but perhaps put off by how his child has been made to live because of the Fel.
After Durotan attempts to form an alliance with Stormwind, only for his friend Orgrim Doomhammer to betray his trust, the Frostwolf clan is purged from the Horde. Realizing what his actions had wrought, Orgrim convinces Draka to flee with her son lest they be killed by Blackhand.
Draka takes Go'el and runs but is tracked down by members of the Horde to a river. Draka places her child in his floating crib into the water and leaves him in fate's hands while she stays to hold off the orc hunting them. She manages to kill him but is dealt a fatal blow in turn, and the last thing Draka sees before dying is her only child floating away and hearing him cry.
Go'el's father Durotan would die trying to defeat Gul'dan in mak'gora only for the warlock to cheat by draining Durotan of his life energy. Orgrim claimed one of Durotan's tusks to give to his son one day.
Meanwhile, Go'el floats further down the river until he is found by a human lord.
