Mulberry Dragon

The Prince Dragon is a... balanced dragon. Tart but also sweet. Usually very forward with the way he speaks. Not hiding how he feels about certain beings or creatures, but he... does play down the opinion if it is possibly too rude. Though sometimes a bit more irritation slips out then necessary.
None of the tart is ever seen by hatchlings or young cookies. None. He speaks with them politely, but never harshly.
No one quite knows the true form of the Prince, and few have seen the half-version. Well, some of the older dragons remember what he looked like, but it's been ages since they've seen it.

He warms the island with his power and keeps secret the thing or being that aids him with that. But a lot of it is his own.

He and his subjects are on a group floating islands (called Drifting Islands) that are chained together and warmed by their Prince's fire and something else... The island drifts closer to the realm of cookies.  And Only gets involved with the other kingdom(s) after certain other cookies make a fuss in his kingdom and with his subjects. He opened up his Obsidian Castle to the runners as a resting place.
