Beastkin are a younger race, descended from the Fey. Your affinity would need to be with a creature at home hunting in the Caverns of the Underdark and for whatever reason you have chosen to make your home here. You could either be associated with one of the Drow Houses or a free roving pack.
Makeup Advice
Beastkin will often opt for a two-tone (or more!) stripe across the eyes. This is created by starting with a wide base colour stripe, then tightly closing your eyes and applying a second narrower stripe across the eyes. The natural pull and wrinkling of closing your eyes creates a more natural tone shift in colours.
Of course, there are many types of beastkin! Another common option for scaled beastkin is to use netting to create a scaled effect when applying their makeup.
Playing Notes
Beastkin often have a distinctive two-colour stripe across their eyes and frequently wear furs. They will commonly be tribalistic and will tend to stick close to their tribe/family. If creating your own clan or tribe background, please submit it to the plot team and they will be happy to work with you to add it to Tarantulan society.
