Thorns were small fey warriors who acted as guardians of other fey creatures. They took their name from the longswords they carried, which were constructed from thorny plants. Most thorns in Faerûn lived in the Dalelands or Cormanthor.
Thorns would attack anything that threatened other fey. They preferred to sneak up on opponents and carried sleep arrows, which caused adversaries to fall into a slumber. They also had the ability to launch a sneak attack.
