Glendar was a wizard and later lich.
Glendar served as a patron for adventurers. They hated basilisks and medusae, so in order to protect them he invented the rod of mirrors.
Eventually, however, Glendar turned evil and became a lich. He was destroyed by some the adventurers he had formerly sponsored.
His rod of mirrors was well known by 1372 DR.
