Abyssmals

The Abyssmals are a collective of deities that turned against life, wishing to break all their toys and start over. Those that fought against them and ultimately bound them, imprisoned them or broke them by the end of The Core War are the deities that are worshiped freely to this day. Someone might simplify them as the 'evil deities' against the 'good deities.'

Generally it is considered immoral to worship an Abysmal, akin to admitting one is a criminal to a murderer - the extent of this depends on the specific Abysmal.
