Blue Eyes (Q. Hendiluin; Av. Nindyâthende) was a wildflower of the composite family native to temperate plains which resembled the marigold. Its beautiful royal blue flowers contained a powerful drug, which when brewed into a tea and ingested enhanced the user's vision, both extending perception range and giving mild infravision capabilities. The effects lasted for 3 hours, or longer. If taken a second time during a single day, however, blue eyes was a strong conversion poison causing blindness.
