"Once, life was wild, untamed, and without purpose. What we have done here is to fix that." -Journal entry recovered at abandoned temple
A bio temple is a structure created by the Immortals for the shaping of life and creation of biomorphs via selective breeding over long periods of time. They are stated to be some of the oldest structures by the great Immortal civilizations.
Many were either destroyed or abandoned during the Great Immortal War, their biomorphs escaped or destroyed.
Bio temples are often found in the middle of or near haunted forests.
