From publisher blurb:
Reach for Infinity!
In the far reaches of the Aurin system, where the distant sun is just another bright star, strange and ancient miracles permeate the cosmos, where the limits of both space and time bend and fray when the power of the mind interweaves with the substance of reality. Titanic mechanical moons have brought destructive change in their wake, and their weathered hulks linger in the shadows of shattered stars and planet-wide storms, yet even so the elder races of dragonkind and the younger folk of the system keep their eyes at once on the heavens above and the wild lands below, ever watchful for an irruption of the qlippoth and their chaos blight that can bring ruin to all. To those daring or reckless enough to delve their secrets, this aberrant expanse beyond the outer limits offers power beyond imagining.
Gleam of Eternity offers a wealth of new options for players, bringing the biohacker, vanguard, and witchwarper classes from the Starfinder Roleplaying Game to the Pathfinder Roleplaying Game, along with nearly 20 all-new archetypes like the biollurgist biohacker, stellar echo wilder, miracle soldier psychic warrior, and worldweaver psion, plus alternate class features and integration with expanded rules systems like psionics and Spheres of Power! You’ll also find over 80 new feats, spells, augmentations, combat talents, addictive power-boosting stimulants, and more to enhance your game, from Revenant Militia and powdered psicrystal to Vacuous Power and Reality-Puncturing Attack!
