Horrors of the Lifechain
This science-fiction horror supplement expands the Lifechain, a strange ecosystem linking semi-divine beings, predators, and other dangerous creatures across deep space. It presents revised Lifespawn from earlier bestiaries, revamped Chyss conquerors, and new monsters for the Otherverse America campaign setting. The creatures serve as threats for heroes and are most effective in campaigns using Lifechained feats and powers, which connect characters to the ecosystem at a genetic level. They can also be used in other science-fiction or modern horror settings as alien predators and adversaries.
