There are many offshoot tunnels like at numbers 1 and 2. Roll 4dIQ. If the roll is made, the party figures, the kidnappers did not turn west but east down the tunnel. Head down the east tunnel.
If the party doesn't make the IQ roll, there is a 2 in 6 chance that the party runs into a nuisance creature:
- 1-4: 50 rats
- 5: 10 scuttles
- 6: ST 12 green slime
or other problem (examples: cave-in, methane gas pocket, etc). This will keep happening until the party makes its IQ roll. Once the party makes the roll, head down the east tunnel.
