The Griseous Order

"A clan shrouded in mystery, the Griseous Order claimed to have been in the lands of Hisui since the advent of the Celestica civilization, although never mentioned directly in the Old Poem.
The legendary founder was Mercurius, one of the first Scholars who studied in depth the Creation Trio but praised especially the importance of Giratina as the powerful being able "to tear through the veil of reality". In the tentative to use such symbolic power for his own people, he founded the Order and leaned into the occult to harness such qualities and, hopefully, take the favours of the Shadow Pokémon.
After the fall of Celestica and the arrival of the Pearl and Diamond Clans, the Order fell into the oblivion, except for very few books left. So far, only three members are known to be alive and active, working in fullsecrecy as their own ancestors."

Created a small mock-up of the Pearl and Diamond Clans's picture with all their respective members altogether, that was quite fun! More informations of the Griseous Order as well while I try to flesh it out better, so that's a plus xD
