This is when an X seed (the orb with an X with little strings sticking out) was taken by Zalgo (the black hairy looking figure) and divided into 13 fragments. Zalgo then turns Hayo into X using one of the fragments. It's speculated the rest of the seed was given to Hayo for further usage to absorb the other 12 pieces of X. It is speculated the other X seeds were killed off in a domino effect along with our timeline's X due to Zukember's sheer power and a time spell of dubious function
