Grelnixar was a powerful, deadly hallucinogen produced by the vrel, a nettle relative native to temperate tallgrass plains or steppes, and emitted through its leaf hairs. Grelnixar caused its victims to run until they died of exhaustion, as did the "Running Death" curse; at minimum, it caused severe hallucinations for several days.
