Enchanter spells in HHK

[Malone88]

I believe all my DEs were KOS there until I did some faction work.
Invis the easiest option.
I believe any good race illusion would also work.
Perhaps casting Alliance/Benevolence on the first guard you see as you enter
the zone would work also, but not sure.

As stated, those two merchants are alone in a back room without
any guards near by. They sell to anybody.
