They wore loose tunics dyed in crazy multicolor patterns, lined with psychedelic fur. They were armed only with tall staves." IPTSF Text 27
Real World References
Their name seems to mockingly refer to High elves of many fantasy settings.
Their appearance and hints on the use of Flower Power also suggest that this type of Elves are often "high" on intoxicating substances.
