There is an Undead One, which could help you.
In one of the very first levels, not too far away from the Orcs, you can see the statue of a woman. She can still summon an undead person to your help.
But be careful not to hit him, because then he could turn against you (like everyone, who is treated unfriendly <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> ) .
And a second note: Getting out of the catacombs means for that undead one (like mslynx said) that this one will be redeemed; because he is cursed, cursed to help you.
