Dragons
This is a favorite category for me. There actually aren't a lot of dragons on Gaia oddly enough, though there should be. Because they're awesome, and staples in plenty of fantasy books. A standard for all dragons is high resistance/immunity to: sleep, paralysis, and poison. They have scales, wings, and are as varied as can be.
For the hotel, even if the alignments don't match up all the time, we have seen a fair share of chromatic and metallic dragons. Even kinds not those. This touches on Dragon Touched, Half Dragons, and full dragons.
Also, all dragons LOVE treasure. Of all kinds, though some dragons are specific in particular tastes.
Tome Dragons - Love. They love books, and love very very fragrant teas. Their scales are typically like that of a rainbow salmon, red and blue and kinda silvery. Their tail looks like a fish tail, and their hair reflects the same kind of color as their scales. They have the hair instead of horns or fins on their head, and it gets quite long. Their eyes go from a sky blue to a deep night color as they age. These dragons have a breath weapon that has 4 choices when they breathe, from a burst of sonic air, to a small fireball, sharp piercing stones and a burst of water. They also learn magic faster than most of their dragon counterparts.
Known Tome Dragons: 4 (1 full, 1 half, 1 slightly more than half, and 1 1/4 dragon)
White Dragons - Greedy and selfish, but the weakest of all dragon types, white dragons are known for immunity to cold and weakness to fire. They like to roost in mountains and frozen wastes, and eat their food frozen. They have an ice cone breath weapon.
Known White Dragons: 3 (1 deceased)
Red Dragons - Usually quite arrogant and the strongest of the Chromatics, their breath weapon of fire is usually the most deadly. Their scales are a brilliant red color.
Known Red Dragons: 1
Copper Dragons - Tricksters in the metallic family, they breathe acid. I think they also have an alternate breath weapon that is like knock out gas. They like humans and humanoids, and there's plenty of descended half dragons or humanoids with dragon blood in them. They also like performances.
Known Copper Dragons: 1 (not fully, kinda...like...1/6thish)
Gold Dragons - Most regal of the metallic dragons with shimmering gold scales. They use a breath weapon of fire and are good to the core.
Known Gold Dragons: 2 (1 dragon touched)
Virons Known: 2
Prismatic DragonKnown: 1
