The tag alias #78065 thlayli -> bigwig_(watership_down) is pending approval.

Reason: Thlayli is his name in the book's conlang, but he's more often referred to as Bigwig: https://en.wikipedia.org/wiki/Watership_Down#Rabbits

Basically, it's the same logic we use with English localizations. Just as we would alias an anime character's Japanese name to its English equivalent, we would alias the Lapine name Thlayli to the English Bigwig, despite Lapine being a fictional language.
