Long story short, it's from the book "Faust" from Wolfgang von Goethe and a musical piece by Lizst but intentionally misspelled ;) (should be s instead of z)
I'm guessing yours has something to do with Sonic?
cool I'm checking to see if i have a spare roost TM in gen4. This might take a minute.
I think I'm just gonna aim for Roost and Stored Power, not Psycho Shift as well. Psycho Shift looks like it would be coming from a Noctowl first and bred onto the eggmove parent for the other 2 moves lol... that would take significantly longer XD
