Return to Ringworld
Walk straight ahead until your party discovers a door. Enter and find
a somewhat cliched scenario with madman and weapon.
After Teal’s premature departure talk to the ghoul protector (it’s not
necessary). Now you can take your pick of two slightly different endings.
Ending 1: Shoot (or at least try to) ghoul protector.
Ending 2: Just step into teleportation beam.
