Personally, I think that animus magic will appear again, since her spell removes current magic, not future magic. I'd say the spell just hides or blocks the magic, and doesn't remove it from animus dragons. If they were to have eggs, there's a 50 percent chance of the dragonet being an animus, and since the spell applies to this generation of magic, the dragonet would be able to perform spells.

I asked Queen Glory for a political meeting, since we needed to discuss a draft for a peace treaty anyways. She's actually pretty nice, so I just told her about the crown. I think she actually gets it, which is surprising. She said she would pass it on to her NightWings, so hopefully none of them attack my tribe.

A cookie? If you mean human sized, it would be as tiny as a speck of dust. Dragon sized, however, would be roughly the size of my palm and be thrice as large as a human.
