This anomaly appears to emit a form of radiation that interferes with the visual cortex of the brain, rendering anyone within it blind. Experience shows that exposure of around a minute causes severe headaches. A corpse found near the anomaly appeared to have died from a brain haemorrhage induced by the same radiation.

• The type of radiation (physics, needs a field trip)
• Effects on plant life (biology, needs a field trip)
• Effects on animals/humans (biology, needs a field trip + test subject)
