Hey all! I'm putting together a Savage Worlds trek campaign and need some help building NPCs. My players are going to be cadets on a semester long cruise, while the crew will be NPCs. Anyways, I need help figuring out how many advances to give said NPCs when building them. Does anyone have a good "x number of years of service=y number of experience points" equatin for NPCs in this system, or general advice along those lines?
