Liminal Lineages is a collection of five new species from The Copper Sanctum. One of which is plant-based and the remaining four have an elemental origin. Liminal Lineages also includes several custom feats for each of them and an assortment of magic items designed especially for the five species.
Ambridi are actually magical trees, but they spend around a century as sentient seeds coated in amber-like sap that lets them walk among the rootless.
Argili appear to be composed entirely of clay, and are able to shape and form their bodies in various ways, including firing parts into hardened armor.
Vasari are nearly entirely water, though they appear not too dissimilar from humans while out of the water.
Vulkari are essentially humanoid-shaped volcanoes. Their skin looks like cracked volcanic rock and they have a molten core inside them.
Whiri are perhaps the strangest species included. They are basically sentient ropes, ribbons, cords, and other similar objects. They have ties to the elemental plane of air and are able to entwine themselves with objects to create humanoid bodies for themselves.
