Godbound - Players are demigods. Think more like D&D level 15+ as the starting point power level wise w/ streamlined rules to make that power level easier to deal with. Due to the power level it's a game more about consequences of your overwhelming power than a conventional D&D "try to survive" game. Also, the core of the game is free. Sits on the edges of the OSR rule set so familiar rules if coming from D&D. Down side is you might find the rules a bit too light.
Witchcraft - Hard to explain this one. Again, the game is better at keeping characters alive to deal with consequences than D&D. It's been a long while since I played it so my memory of the rules is hazy. This is one I suggest you read the Drivethru entry. If that page entices you give it a try. If not pass it up.
Swords of the Serpentine. This one is a Gumshoe game. Straight forward rules. I like this Gumshoe vs. others as the rules to use investigation skills in combat makes it pretty lively. While you could make it deadly, I find it a lot easier to calibrate away from unexpected character death than something like D&D. Good medium crunch rules and easy to extend with out Gumshoe game systems if you want more complexity. I'll add generally in Gumshoe player characters start out generally competent, which is a personal preference.
Tephra - Um... I was tired? I'm not sure why I listed this one. It's an interesting d12 system, but on reflection nothing stands out for your scenario.
hope this helps.
