Traits and other biology:
Luminescence:
The glowing bands on the shaderians skin is a result of a mineral compound in their blood that can use energy very easily resulting an easy use for magic and also allowing these glowing patches, depending on the magic they use it may or may not affect the color of their glowing skin (multimagicians luminous patches are only one color)
Digestive and respiratory systems:
Shaderians breathe in oxygen gas but they can also breathe in a few other things and separate oxygen out of it such as water vapor. Their digestive systems can dissolve things faster due to the mineral mentioned previously but not incredibly fast, shaderians aren’t harmed by ingesting lead on accident but are harmed by ingesting cobalt.
