Concept sketch (with a quick messy internal organ ref) for whatĀ unicorns are like in Sinirin. I monotoneād the picture up top because I realized I didnāt really likeĀ how Iād coloured it.
The unicorns of Sinirin are not animals - they are planimals, a separate (though at times very similar-looking) kingdom of life. As the name suggests, all planimals have a mix of plantlike and animal-like features: like plants, they photosynthesize, breathe CO2 and exhale oxygen, and make use of plastids, and like animals, they are mobile, have phospholipid cell membranes instead of cellulose walls (though some groups do make use of cellulose, itās never the majority component in their body structure), and have animal-like tissues and organ systems. They rely heavily on the uptake of ambient magic to enhance their naturally inefficient biological processes, which has lead into many planimal species developing some form of active control over magic.
Unicorns belong to the phylum Xylochordata, chordate-analogues that have cellulose only as part of their skeletal structure and make use of a number of different photosynthetic compounds, occasionally multiple within the same species. The compounds are found in theĀ āfurā and āpetalsāĀ that grow on the backs / tops of their bodies, aka the areas most exposed to the sun, with the rest of the body being pigmented with mammal-like forms of melanin. Havenāt decided whether unicorns should use chlorophyll or carotenoids.
The horn of a unicorn is actually a highly elongated, hardened petal. They are naturally inclined towards light magic, and a rare few can perform healing magic as well.
Unicorns do not eat, so their mouths are only needed to drink water. As a result, the mouth cavity is quite small and lacks teeth, though they do have a long tongue that naturally forms aĀ ācupā in the middle when extended.
They live in lower-density forest regions across the continent of Ael.
