If you would like to start the game in the Moderated freeform section, I or another admin will have to give you, fletch and anyone else who wants to join, permission to post in it.
I would like to see the details of this roleplay progress in this thread before I allow you to start it in there - just so you have a defined idea.
Now, onto my opinion.
I believe that you need an 'end goal'. Something to strive to, even if the players don't have to know it.
Might I suggest something?
What if - when the players flee their old world into the new world - they arrive in a meadow with no town or civilisation of any sort around. What they DO find, however, lying on the ground, is a broken, rusted sword. This sword shows that there is intelligent life on this world!
Now their goal is to find any form of civilisation. The nearest town could be miles away in any direction. There are unheard of beasts and strange magic effects in this world, but in all, the world seems strangely quiet...
I have a bit of a twist, which i'll whisper to Nos, in case he want to use these thoughts - Don't want to let the players know beforehand!
