Entropic Cascade

Ω Entropic cascade failure is a side effect that can sometimes occur when travelling to an alternate reality. It is caused by the increased entropy created by multiple versions of the same sapient being in one reality. The effects, which only affect the non-native versions, continue to get worse over time, eventually resulting in death. The only way to prevent this is for them to return to their own reality. Entropic cascade failure, for unknown reasons, does not occur if the sapient being's counterpart in another reality is deceased. It is marked by violent and painful convulsions as the foreign matter (of which the being is composed of) is, in effect, rejected by the host reality. ♎
