Get your master to buy and then give you a mount (i.e. - they release their mount for you to claim). Or use portal stones. Or, as is really the intention of these setups; the slave should be at the master's side whenever possible - so the master handles the coin and pays for a caravan to X, or lodging in tavern Y, or sell/buying items from merchant Z. Life as a slave is, and is meant to be, difficult and these things are in place to re-affirm that the person is less than even a free elf or gnome - and reliant on their master. If the master isn't around, it's up to that person to have provided enough for the slave to be (somewhat) self sufficient until they meet again (assuming the PC slave will be played when the master is not logged in)

I'll point you to some comments I made in regard to surviving as one from a thread made not long ago. The part in bold is emphasis by me for this topic in particular because I feel it is is especially applicable to this thread as well.

This is not a problem.

First, you will never die from lack of sleep. Becoming fatigued results in ability score penalties, with the worst that will happen if you succumb to exhaustion is that you doze off for a few moments at in inopportune time.

Next, if you're talking about a PC slave wandering around, that means he/she has a PC master. Their PC master needs to provide for them - this slave-being-a-pain-in-the-ass setup is intended to reinforce to both master and slave PC that the slave is not just another free-roaming individual. The master should, at the least, probably buy the slave flint and tinder and a bedroll. The slave can harvest some dry wood and setup camp outside a 'civilized' area if they need to rest if their master isn't around.

Finally, if you're talking about Thayan Gladiators, it is intended they only rest in the Ludus Magnus which is their life and home when they're not bleeding in an arena or training somewhere. Or if you're talking about escaped slaves (arguably the most difficult faction/concept to play in this PW), they have a special merchant who provides the camp necessities to them, as well as a faction stronghold that has a free resting spot for them.

Further discussion or suggestions for change as to how PC slavery is handled should be sent via PM to Sundraoi.
