Hm, swordmages are in the FRPG, right? I might go with that instead of fighter. Still would like to know about making a hybrid character, though. (For those who don't know, hybrid characters are more like the 3rd/3.5 multiclass characters; you pick two classes and get some of the benefits of each, but most class featurs are weakened somewhat. For powers, you can pick from any class's powers, but you have to have at least one at-will, encounter, and daily power from each class.)
I'll need to do a bit more research before I post a bio, however, since I'm not actually familiar with Forgotten Realms. But I'm thinking either elf or eladrin swordmage, potentially hybrid into something else depending on if it's allowed and what else is in the group. I'd like to go with Aegis of Assault, but that build more or less requires we have some characters that would benefit from enemies provoking opportunity attacks (the idea being I mark something, then run across the battlefield so if it attacks someone else, I teleport in and whack him, and if he comes after me, everyone else gets a hit in.)
