Dark Light Dwellers (UN-D-7983)
The Dark Light Dwellers are thought to be accidental travellers. It is believed that they are drawn to our dimensions by energy rich locations such as nuclear facilities and power plants.

They usually find their way back to their own world without incident, and may not even comprehend that they have crossed realities.

However, occasionally their visits are not without consequence. Though their intentions are not believed to be malicious, due to their very alien nature, the mere presence of the Dark Light Dwellers in our reality has inadvertently contributed to several near disastrous occurrences that highlight the dangers inherent in crossing dimensions.

An incident in the early 1980's occurred when one of these creatures was drawn to the nuclear power station of Calder Hall at the Sellafield plant in Cumbria, UK.
