Two-headed Lindwyrms are a strange breed that are usually only seen at night—especially when the moons are full and they feel their vigor is at its best for hunting. The rest of the time, these dragons are well-hidden deep within caves or crypts; they enjoy sitting in dark places. Each of their heads has a different mood and personality than the other, and since they have different brains, they rarely share the same thoughts—and never the same pain. They are so fully separated, one head can be asleep while the other is awake.
Two-headed dragons are unique enough to deserve a separate classification from ordinary dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.
