Hi there, Milktank! Unfortunately, the game you are talking about doesn't seem to be an official one. As such, we're keeping discussion of it to its specific thread over in the hacks forum (or if it's not a hack, the Game Dev), in case there is one for Reign of Legends there. Take a look! If you don't find it, I suggest you look for a thread about it in another forum than PokéCommunity.
Hope you'll stay as a member here and post about other things though! :3 Message me if you have any questions regarding the forums.
