At some point I got lost in my thoughts, memories from the past started to surface in my mind and several things started to make sense.
The reason the World Tree that I met for the first time asked me to save the World Tree of the Dark Continent, the event that saved Silvia, the power of chaos was instrumental in transforming her into a different creature and also helped the new World Tree who took his place in transforming the remaining power in his tainted, dying body into his own power, allowing the new World Tree to grow rapidly.
So many things in my past didn't make sense, at first I just thought it was a magical world as I didn't understand how it all worked, but now looking back with what I know I can notice the pattern of events and those who noticed what could when I myself was in ignorance.
