usually to leave the town you go out the front door but in bergen hotsprings instead of going out the obvious front if you go to the right there is a little hill and if you stick close to the wall and keep walking on the hill you port outside to nebo terrace even though you didnt go out the front door...

yea it works but its not worth premium since it does the same as going out the front

Yes, sorry, but this information is of no use. Better luck next time.
