Well, they [rarely] drop Souvenirs of Reprisal, so perhaps they were servants of Velka, but did a Logan, and tried to become more like them?? Whether they were Pardoners or Blades of the DM, I don't know, as it's speculated that Velka originally led them.

They were obviously exiled to Ariamis because they were important to some degree.
