The Princess Is Vanessa
There are countless theories which suggest the Princess is Cassidy or even Cassie, however they don't really hold up and Princess Quest seems to point exactly to who the Princess is.
So while Cassidy as discussed in a previous post is probably not the Princess, how about Cassie? Well.....
In the Princess Quest game you collect up not just a Vanny Mask but a Glitchtrap Plushie. Both items we know has only been associated with Vanessa, while Cassie has only been associated with Vanessa's Vanny Mask. Adding onto this the Princess Quest game was created in-universe before the events of Ruin, and involves Glitchtrap and has some parts of it being similar to the Five Night's At Freddy's VR: Help Wanted locations and not what we see in Ruin. Cassie themself never interacted with Glitchtrap but Vanessa has. Written by Eris
