Sir K, verily, since it's late October, hope you soon find your way out of the sands into an Oasis with broadband and drop us all a line on how you're doing
I see from the above that you haven?t decided yet, but, hopefully, Brythe will not leave if PC changes his alignment from N/G to E later in the game after recruiting him?
Although the game somewhat pigeonholes evil characters as equaling randomly violent, kick children in teeth types, when I roleplay LE characters, I always prefer to do it in a ?Palpatine-like? fashion. Seemingly all reasonable up-front, give the slave children 100g etc. until it is time to strike and strike hard.
Brythe seems an ideal subject for an ?Anakin-experiment,? being very reasonable and understanding to him (i.e. talking the good-path talk you write) but subtly having him commit more and more evil acts. Now it may be that you will script him so that my evil PC will fail abysmally in trying to lure him astray with a smiling continence physiological game, but roleplaying such an attempt should still be hella? fun.
