Triomni Charonian Unicorns

The Triomni Charonian Unicorns are a hypothetical race of omniscient, omnipotent, omnibenevolent unicorns that live in the subterranean caverns of Pluto's moon Charon. Those who do not adhere to the will of the TCUs are condemned to suffer eternal torment in the lava-fields of Mercury.

The Triomni Charonian Unicorns are commonly used to demonstrate the concept that the threat of eternal punishment is only as effective as one's willingness to consider the consequences to be an actual possibility. Eternal torment in the lava-fields of Mercury, for example, would be a truly terrible fate were it an actual possibility, but if one does not accept it as an actual possibility, then one would not behave according to it as a threat.
