The changes I made on November 16, 2017 were based on the storyline of Kaiser in the early levels just before departing to Maple World. I was just simply playing through the Kaiser class and I noticed that the NPC Fenelle provided some information on Transcendents. I was surprised as well since I didn't really notice it before. So the gender of Chronica, the changes to Aiona, and the explanation given by Fenelle included in the page are according to the NPC.
I just replayed Kaiser's storyline and there seems to be an inconsistency in Chronica's gender. When explaining the origins of the interdimensional portal, Fenelle says "Darmoor attacked the transcendent of time, Chronica, and took herpower", but later she says "Chronica is the transcendent of light, but little is known about him. Darmoor confronted Chronica in his sanctuary..." "...Chronica refused, and so Darmoor sealed him away and stole his power". This could be a translation error as Korean is gender neutral, or it could be lazy proofreading.
¯\_(ツ)_/¯ classic Nexon.
Thanks for your help!
