I needed a script that could teleport the PC from location to another, similar to the way the StarGate system works. ie. The PC comes across a LandGate and notes down the combination of that gate, I chose colours determined by placing coloured shafts of light in a Menhir with a Dial placeable in the middle. Upon clicking the Dial, you start a conversation with it which allows you to key in 3 colour codes and then will teleport you to the destination if it is valid. Unlike a portal stone this allows you to teleport to any destination, provided you know it's combination designation.
