He's in control of the Shantay Pass.
Sells desert clothes and items to help survival in the harsh desert conditions.
You can also use him to teleport to Port Sarim in the following way:
- Talk to him and say "What is this place?"
- Next say "I am definitely an outlaw, prepare to die!" (you'll be imprisoned in the nearby jail)
- Next say "Deport me to Port Sarim!"
You will then be at Port Sarim jail, in a closed cage. You need to pick the lock (a picklock is not required) to get out of jail.
