A big thanks to everyone for stepping up in my absence and helping Aristo with his character. 

Just to be clear about the ages and the siege of Veiron:
This game is a reboot, we tried this before the guild was wiped, it died, but me and Vlad loved this enough to give it another chance. But with a few alterations to make it better. In the old version it was clearly stated that every character had to be at least twenty years old because that's how much time had passed since Veiron. Somehow this short line of text disappeared while it was being edited and neither of us noticed until Parker pointed it out. So instead of having everyone change their characters I improvised that Veiron had been besieged for the last twenty years (or so) just to keep things moving. It's not a good explanation and I wish that we had noticed this error sooner, but like Parker said, we've silently agreed not to talk about it. 

Now, let's talk about Khagor.
To start with (And I know this has been said) The mark.
The mark is a small thing (or at least starts out as it). A detail. A black mark somewhere in the body, birth mark, a cut that never heal, a paralyzed toe, a patch of white hair. Something along those lines. 

The beastmen(yes, this too).
Very little info has been given about this race and I appreciate your attempt to flesh out the world, but I'm afraid that your story isn't really believable. Though I believe it would help a lot if you'd set the time for this “change” a long time ago and not in our characters life time. Also I have to agree with Parker that the demons wouldn't give out traits and advantages like that without getting something in return. Give it a thought, I'm sure you can come up with something good. 
Now, the beastmen isn't really one race, more like a gathering of half men/half animals. They've only been put in one group like this because they all share that trait. 
As far as appearance go I wholeheartedly support the humanoid rat. 

One thing just hit me that could solve this problem without forcing you to change most of your character. How about being cursed by a powerful mage instead of demons? Perhaps a mage who fought for Veiron saw Khagor loot something during the battle and, enraged by it, turned him into a rat. Then the curse spread to his men and so on...
Perhaps “real” beastmen has some strange reaction to your character. That could become a big plot-thing for you. 
Just a suggestion. 
Other than that I believe Vlad, Parker and Melkor has thought of everything. Don't hesitate to ask if you need help or advice on anything. We want good players with interesting characters and will help anyone who asks to achieve this. 

Melkor:
I'm currently working on the post which will bring our characters together, but I can't really do it "right now" (in-game time). Travelling from Rudin to Astoria will take a while and I think I'll have to do something on the way just to get some time to pass. I've had an idea for a small encounter that I can use, so you can just go ahead and figure something out for your character to pass the time as well.
