(Cerulean) Festive Unifier Siblings

Lore
Hero! Thanks for celebrating with us! I'm sure that the humans and Cryptids of Neotellus are overjoyed! "You must have met a lot of Cryptids up 'til now, right? I know you'll meet many more to come, too!" "We're looking forward to celebrating again next year!"
