hello i have been creating a campaign in the doctor who universe using the dnd system with some adjusted mechanics, and i need plays (4-5)

here's how it will work

the campaign  will be structured with plotlines that will last one to two sessions accompanied by an overarching plot

one player will be the doctor, 1-2 players will be companions and the rest will change characters every plotline and be the guys who will be in whatever place the doctor is travelling too they will have insight on what going on and help the doctor for those two sessions until the plotline is done and they will make new characters to fit the next plotline

every 30 sessions or so the doctor will regenerate and another player will get to be the doctor and everyone will rotate roles, so everyone will get to be the doctor or a companion at some point 

thank you for your time😀
