[[WMG: Xix's actions after being turned into a Undead]]

* It is possible that Xix was acting under the influence of Semek for a period of time after [[spoiler: Siana]] resurrected him, hence why he was so powerful as to know how to kill the knights quickly, why [[spoiler: he tore out Siana's heart and took it into his body]] and was how he was powerful enough to [[spoiler: crack Caladbog's shields ]].

[[WMG: [[spoiler:Siana]] is Nex and Serin's only child]]

* It is possible that [[spoiler:Xix]] is a red herring [[spoiler:and only passed the blood trials because of Siana's heart]] and [[spoiler:Siana]] is the real child Serin left behind before her capture and imprisonment by Nex.
* [[spoiler: A bit more than possible since it was shown that a woman resembling Serin dropped off a ''single'' child instead of two. And of the two children, Siana chanted a signature spell of a Necromancer, raising Xix as an undead.]]
* Jossed: [[spoiler:Ninurta is revealed to be their son in [[WhamEpisode Chapter 125]].]] The circumstances behind this are unknown.
** Also, Hecadoth's foresight stated Nex had only one son, and Serin's the mother.
