Valgoth the Invincible.
Ftr3/Paladin15/Divine Chamption of (Lawful Good)10.
A very traditional knightly type, Valgoth isn't the most intelligent of people. He's good natured, somewhat naive, but stubborn as a post. He tends to act before he thinks, which is
almost always, and hes one of those people.
You know. The ones that everyone looks to in a moment of crisis.
The problem is he often hasn't a clue what to do in that moment. He thinks, unfortunately, with his heart. And he's unlikely to think twice when he notices evil at this gathering.
Think traditional knightly type on his dragon, entirely caught up in the affairs and hasn't a clue what to do next. He is a man of action, and due to the fact he is upset he is very likely to create it, hoping it'll work out for the best. He just wants to go and hit things.
The more the conversations get bogged down, the more frustrated he will get. He'll likely leave at the first suggestion that might do something, or if he's forced to converse with an old enemy (or new evil) he'll often start fights.
The problem, of course, is that he is entirely too powerful to be dealt with easily. He's got the kit, the money, and the saves to cope with almost everything.
Plot Hook: Valgoth rocks up; PC's have to somehow prevent him from causing the entire conversation to explode with lightning death from every quarter. Valgoth will likely pick fights with whoever is nearby, assuming the "evil" characters (ones he can detect) are conspiring.
Valgoth is that annoying fire-starter that gets everybody going at everybody. There's so many NPC's here that would normally kill each other at first sight that it won't take much to set them off. Valgoth is the perfect fight-starter.
