Currently, I'm RPing as an Ishgard born Elezen Dark Knight. My question is, do people become Dark Knights just by grasping that inner darkness or can it be caused by say "A scholar embraces dark Aether" scenario? So far, it seems people become Dark Knights for various reasons. Like when people in power abuse it. Any insight would be awesome. I am still new to the lore. I have read some stuff on FFXIV Wiki too, just need a more solid answer.
