I remember playing through the quests when Enedwaith first was released, and I remember my eyes went 'WHAT!?' when I read some of the quests concerning the Bugans... but I don't remember what caused my reaction.. so.. can you help me? not with remembering my thoughts, but explaining to me.. as best you can, what they really are, as I think there's some confusion to that, lore-wise...

Are they

* Hobbits corrupted into "half-goblins"
* Simply hobbit brigands
* Some other creature?

And..where do they come from?
