From publisher blurb:
Welcome to the realm under the Viridian Veil! Here in Devonia, humans, dwarves, elves, orcs and gnomes never let the waves wash them away. Instead, they adapted. Of course, each had their own unique way of doing so! Viridian Veil is a temporally mixed up domain where aquatic dinosaurs mingle with civilization, primordial beasts fight futuristic menaces, and strange chronomancy magic permeates every drop of the strange sea. Inside this tome you will find rules for fantasy aquatic time travel, adaptions of existing marine races, as well as several drylander races that have gone aquatic. There are new spells, feats, prestige classes, mundane items, magic items and a new class (the sharker). There are also tons of "fluff and crunch" on the realm in true Alluria Publishing style with full color art. To top it off, we included a bestiary of over 40 new aquatic monsters and animals to flesh out any "Isle of the Lost" style setting.
