On 7/19/2004, a player claimed that this NPC "used powers before they were bugged." 
A player stated that you can, "find Force Crystal Hunters usually to the west of the Imperial Outpost all along the left side of the map..." He also said, "you can usually find 2 of them huddling around the shrine right outside the Dantooine Mining Outpost."  Another one stated that 2 of these NPCs could be found at a "buried arch at 897, 1393" which is about 2000m from the Outpost. This is screenshot #152 of my POIs. 
A player claimed that this NPC never dropped crystals and said there was a debate about why an NPC with this name would not have them, but would drop Holocrons. 
A player stated that one of these NPCs used Force Lightning against him in battle. Another one claimed that they "wield lightsabres, do force-lightning and use force choke."
