>ignores lore presented in TWO games to sperg about her headcanon
Cogita is Cynthia's ancestor anon. The only way for Celestic town to be "the oldest settlement in Sinnoh", would be if Cogita's Ancient Retreat grew in size, as Hisui became Sinnoh and more people settled the land, due to Cogita witnessing the arrival of the Diamond and Pearl clan forebears. And given Cogita is the image of Cynthia or rather, Cynthia's the image of her granny, (the Elder of Celstic town and the most knowledgeable person in Sinnoh on its myths and legends), Volo cannot in fact be a direct blood relative to Cynthia, leaving him a cousin or uncle of varying degrees of separation.
Can you fucks play the games, instead of play with your pee-pees?
