First of all, thanks everybody for the help.
As somebody suggested, I hung around for a while and eventually went back to Pelvale. Although I`d been there before, this time I had to explore the area as though it was the first time (The area was dark until I`d explored it).
At last a bandit (Telvel) got into conversation with me and I persuaded him to take me to the bandit camp. Problem solved!
On another subject,
I was in a cave in Cloakwood, having just killed some Wyverns, and decided to rest my party. I was awoken by some Wyverns so I killed them also. I tried to rest again and was... yeah, awoken by some Wyverns. Well I did this for ages at 1400 ep per time and eventually ran out of arrows.
When I went back to Beregost, I got 500gp for the first two skulls and 200gp for the rest.
I dont feel guilty about this little cheat, cos they shouldn`t have messed me around in the first place!
Once again, many thanks,
Davfra
