Implicating sergal → vilous
Link to implication

Reason:

Sergals are species of the fictional Vilous universe.

This universe has a number of other species as well, including the tags:
agudner
nevrean
talyxian

As well as a few others, plus a few subcategories.

Sergals are by far the most popular of the Vilous universe's species, and the most widely represented independently in the furry fandom, but the Vilous subfandom has a very dedicated following.

I'm in the process of trying to organize what's here, and having one 'vilous' tag to automatically unify all of the vilous universe content and other content inspired by it would make it both easier to organize and more accessible to the masses.

I'll start with sergal, and move on to the other species as more of it makes it onto e621.

For reference, here's the Vilous wiki page on sergals: http://vilous.net/wiki/index.php?title=Sergals
