Heavenly Father’s spirit child who proposed an alternate plan of salvation. After Heavenly Father rejected it, Satan rebelled. Heavenly Father sent him, along with his followers (demons), to outer darkness. They lost forever their chance to obtain physical bodies and to continue their progression to godhood. For many Mormons, Satan is the spiritual being whose presence they are most aware of.
