Re: OOC II
I tell him to fly down the tunnel until he reaches an intersection or for two hours. If he comes to an intersection, he should pick one path any fly down it for half his remaining time (i.e. 30 minutes if he comes to the intersection after an hour). Then he should return to the intersection and fly down the next option for the same length of time. If he comes to any additional intersections after the first, he should follow the same rules. After 2 hours have passed, he should fly back to camp.
Basically, in four hours, when Lucien wakes up, his familiar will have spent four hours exploring the passage as efficiently as possible.
