Mudwings

MudWings are one of the seven Pyrrhian tribes. They can hold their breath underwater for a hour and are immune (not actually immune, as fire does still hurt them, although it's scaled down by a ton) to fire. Their color palette consists of shades of brown, red, green (was in THE HIDDEN KINGDOM's graphic novel), and grey (was also in the THK's graphic novel). They can breathe fire if they are warm enough.
