The population is increased when a gathering takes place, and a trait from each unicorn present at the gathering is combined into the new foal by means of magic.
In the wild, unicorn gatherings can have as many as 100 unicorns present. But the adopted unicorns usually gather in a ring of a maximum of 5 unicorns.
Halini Unicorns are large unicorns, usually a little taller than the average sized human adult.
Most have large wings.
Some may have small wings- small wings often cannot carry the weight of the unicorn. Unicorns born on special occasions have no wings.
Halini Unicorns ALWAYS wear a gold collar with a jewel engraved in it around their necks.
Some unicorns may wear jewlery on their wings and legs, but Halini Unicorns ALWAYS have it on their necks.
If there is a unicorn that is not wearing the necklace, that means at some point, it had done a bad deed and was shunned out of its group, or that the group it was born in shunned it away. These Unicorns tend to be very secretive and not talk about their past, as not thinking about the moment keeps them cheery.
