Okay. I'm gonna spoil something:

In the original DA, there's a phoenix known as Richard. He's Milloon's (which is now Miles, since Lugia doesn't want Miles hanging around anymore) best friend, as well as his boss in the Central Disease Foundation.

Basically, later on, it was planned for him to do some research on the species and give vital information to everyone in our group. Unfortunately, that never happened because the RP died.

So, really, that's already been filled. Depending on how much of the original story we modify.
