Technically, this active scenario I have with Velvet is an AU! I had to change some things to make playing Sgrub viable, after all, since they needed to all be around the same age.
There's also the matter of several of these OCs not existing prior to this! Very spur of the moment thing I am going with my gut on.

used to have a humanstuck au for lux and it was p fun until the person i was doing it w dropped me. weh
