Burgundy

It would only make sense that a guy named after booze got a highly drink-worthy dragon. Something the Healing Den didn't make note of in her description is that she smells delicious, and depending on which part of her is nearest to you, different scents come wafting through. Burgundy thinks that she is absolutely the best thing to ever fly. She's quite big, too, but that's never bothered anyone. While she's very long, she can curl into a tight coil and be almost the same size as, say, a medium brown sized Pernese. As she was an adult when she arrived to the Den, she's clearly got her mind set on bonding with Burgundy - no haphazard egg-breaking for her.

As party-hardy as Burgundy is, he's also quite good with his studies. Since his mother is, y'know, kinda pretty smart and all, he takes after her in many ways. She does not give him preferential treatment in the class he takes from her, but he also doesn't need much in that regard anyway. Any of his tech based classes he absolutely aces.

When he gets to the Rookery, Burgundy is in charge of entertaining and keeping people occupied, but also he maintains a shift doing protective sweeps through the area's electronic perimeter. Because he can almost instantly convey electronic information, he can inform other colonies of any incursions quickly and safely. And because he can literally turn into light - he can do it in person if needed, instantly. Though he can't teleport, he can be there as fast as light. He uses his mother's Computational Topography class to actually make detailed maps of areas he might visit that way - he is his own detection and recording device.

Atunl only enhances these abilities. After all she can bend light and breathe it, practically spitting him out where he wants to be if they're flying overhead.
