I have an old custom NPC, hired before new system was introduced.
(So race and name were random)

Would it be possible, to have his name changed (as in new rules/options), after paying for such a change in CPs?

Hmm, I would say its possible. I'd want to check with Jesfa or someone but personally I don't see anything wrong with it. Has it got a custom image already, or just a standard one?

Yeah, custom image already attached. Years ago.
I know it probably would be easier to get a new NPC, but not only this one's special to me, but also has 9 unused skill points (max You could get with old custom types)

ID# 410581
Name: Roy Odan - I'd love to change his name to Emil Noris.

Done.
