After several years without speculation, the Wiki of Costelians is created. (it has been months since there's no Costelian/fakemon ROM hack stuff)
If you wanna contribute to the wiki, highly recommend to talk in the message wall. Please note this is work in progress (aside for the characters (humans of course), realm and Costelian listing, elements etc.
Some are there came from the previous versions of the game, hence few of them scrapped since few reasons why I replace them. (see the official doc for more info)
rest in peace Gastorbeak and Nauticorn, you'll be replaced with unique-typed fossils.
Perhaps why it is themed after Pretty Cure?
The answer is none other than Glittergleam.
Glittergleam is the reason why I've been started to like this Costelian (since because it is based of cure blossom on the magigleam's comment section) but since Amy0501 (aka Amy0503, which is Amy's new account) disabled her account, and I replaced with Miitsudoki (alongside with Magigleam and Magigi with these based of cure sunshine)
Version 0.90 is the upcoming update so please wait for the recent version since it takes months since I done the following:
The only left is menu sprites, move tutors, anything that I need to add however, since it has the most frequent stuff that originals had. (aka FireRed had, expect Trainer Tower, it was removed due to bugs and glitches)
