You look like you need some light, Oiseau
I cast Dancing Lights in it's 4 torches form. One I set to assist Oiseau in his search, the other three I send 50 feet down the tunnel in a 10ft spaced line; 10 ft between each light, so the first light is at 40 ft, second light is at 50 ft, and third light is at 60 ft.
