I came to ffxiv almost directly from ffxi. My character name there was Driven (originally from Hades).
When I switched to ffxiv I had planned to just name him the same name. In my mind, I just wanted my character to be the same one moving on to a new world and new adventures. But I also around then became a new father IRL.
So, the “new sentimental dad” in me decided to kind of combine the names of my ffxi character and my son’s name - Aiv En.
I’ve had no regrets!
