Interesting the telemental/telepathy ball connection with PSIV.
Crystal balls always allowed fortune tellers to foresee the future. It happened in PSGaiden as well as in PSIV, where Mito (the fortune teller) also had a crystal ball that was emitting "a strange kind of glow" and allowed her to see the future. Even Damoa (a fortuneteller in PS1) had in his possession a crystal (shape not mentioned).
There was also a fortune teller in PSIII but he only used tarot cards. Fortune teller in PSgaiden could also use tarot cards or inspiration, but it was not as good (clear/accurate) as a crystal ball to see the future.
Regarding to the picture of the image of the day: Maybe Lutz was watching the events (and future events of PSI)... I don't know, I didn't played this version, but for sure he was always finding new and better ways to grant him eternal life (ironically what La Shiec wanted). It was not the first time objects like that were used to store spiritual things.
I also think there were some great improvement over these graphics:
PSI version ------------------- PSII version (ruins)
Regarding to Myau's height: I'm not sure, but Myau seams to be a little shorter in PSgen1 comparing to PSfanbook, the original PS game and PSIV:
Btw, I don't know if Myaw continued to wear the bottle on his neck... or if he/she will take it off only after the transformation event, but in the end of the game he/she do not wear it anymore. (I'm also noticing that in this pictures, Myaw has "girly", eyeliner, eyes)
Interesting how different Myaw was drawn here. He looks like a rabbit and her/his ears nor his/her tail don't have that black flaming fade in the end (like Rika's). I don't know if the artist is the same from PSfanbook, but if he is, he improved greatly in just 2 years.
