I've seen all kinds of nonstandard pronouns used to refer to Vaarsuvius. Stuff like "Hir" "Vim/Vis" and "Shim". These stopgap pronouns are awkward, confusing and ugly.
We should be using
Spivak pronouns to describe em instead. They fit better into normal English, are easier to parse, and look more natural than the hybrid pronouns we've been using. For example:
"Vaarsuvius read hir note aloud to hirself"
vs.
"Vaarsuvius read eir note aloud to emself"
