Dangerous small flying pests, also called Trielzerai by an illustrious githyanki knight visiting Pelion. The name, among other things, stuck. Two-headed, finger-sized, ear-buzzing flies without any sense of preservation and an annoying blue-yellow shining coloration come, day or night, to pester travelers in the less visited sands. Curiously, the only thing they seem to avoid is the smell of blood.
