First of all, I want apologize that I haven't posted much here lately.
Reason is basketball and studies, which have taken all of my spare time. I've hardly had enough time to make quick visits on Spam Factory, and even those have been VERY short visits, 5-30 minutes usally.
So, to the point.
FIrstly, if I don't comment iun this post something you think I should have, please notify me with post or PM, it's just that there have been quite much posting between my visits
1) The whole campaign is situated in one island, in Forgotten Realms. The interesting part is, that even when the world is Forgotten Realms, you can't find this island in any map, cause it's my own creation.
So, how have you got there? The whole group has arrived with trading ships, most of you in same ship, except Magrus (

), so IMO you have either meet earlier or at least get known eachother during that trip. WHen you have arrived to the island, you travelled to small city called Isthiar, which is the start location of the campaign. If I'm even specific, the starting location is tavern called Isthiar's Rest, which is sitated in the center of the city.
The year is 1374 (Thanks Rav

)
The following is only my idea how Mag has joined your group, you can think of it on your own, or you can use mine idea:
Mag's character arrived with earlier tradeship, and by accident arrived to same city as other group (Isthiar). When Mag was spening time in the tavern, trying to figure out what to do next, he noticed the rest of the party arriving, and got idea that maybe he can get some action by joining their group.
So, mainly I'm giving you the responsibility to think the reasons why each character decided to travel that lonely island, maybe they heard some interesting rumors or were jsut bored enough and decided to take first ship which left, regardless where it was heading.
I'll include some maps and make the thread later today, when I'm at home (I'm currently posting this in university

).
Here are some rumors and such which have something to do with the island (that doesn't still mean that those have something to do with the campaign itself

):
1) Rumors have spread that there is large army of Orcs camping near the city of Isthiar, planning to conquer the whole island from humans. Humans, elves and dwarves have tried to chase that army away by themselves, but because there are some different opinions between those three races, they haven't allied, so they haven't succeed of driving orcs away.
2)Few years ago markets started to get some very good quality items from that island, made by local dwarven kingdom. It's said that they have found very rich source of iron and mithrill which is also very high quality.
3)Local elven kingdom (which is somewhere inside the Forrest of Earel) is arranging great feast for all their elven cousins (except Drows) to celebrate their new king.
4)City of Isthiar has problem with skeletons and other undeads. These problems didn't exist before several months ago.
Okay. at this point I will also add, cause it's actually quite important to you know, that at the very beginning your party will get NPC member, which is under my controll, but acts as any other PC, same rules apllies to him also. But more of that later.
@Mag:
Sorry forgot to answer you, your plannings are okay.
