[@Le Fay] Na, it's fine. I haven't been personally affected by anything that was related to the backstory, but some have been.
For the Digimon: It's not a big deal. If it were one of the planned antagonists, I'd have to ask you to change it. That's not the case, so you can do whatever you wish. I was also thinking of potentially suggesting Goldramon myself, or possibly Magnamon or Magnadramon. Either way, it's not as big of a deal.
When it comes to Mokoto, I'm waiting for a second opinion from my co-GM. Dual validation, and all that.
