Ponyfinder has apparently decided to head underwater in their new expansion: Seas of Everglow. As with all of their previous books, this one includes new races/ancestries, subraces, spells, archtypes, feats, monsters, towns, cities, and more! If you've followed tabletop RPG's at all over the years, you know what to expect.
You can read about the storyline over on their Kickstarter page. I'll slap a few images down below of the new snail race!
