to put some BoS npc in i require -
1 BoS Trader - one for guns ammo armor and weapons in the armoury
1 BoS Trader - for the surgey selling meds
I would also want a few brotherhood just wandering around the place interacting with things like sleeping and eating in the barracks
someone patrolling the corridor, scribes in the command room and a named npc leader in the holding cells.
ONLY if possible could you give the named BoS leader a quest similar to The outcast collection agent?
