Here's my attempt of making Solomon Kane for Folklore using the rules in the Adventure Creation Kit. There's a Solomnon Kane game coming to Kickstarter in June so there will be a read made miniature available in a year or so. Overall, I feel like this character would fit well into the mythos of Kremel.
Ghost Powers: Energy Drain Holy Wrath (2) - Inflict 1d4 Damage to one creature and make them IMMOBILIZED. Impede (1) - Cause an enemy to become IMMOBILIZED 5 after you successful attack them. Spirit Veil (3) - Make an ally untargetable until the end of your next turn. ----- While Kane has the Holy keyword, I think you'd have to look at the prayers and decide which ones aren't thematically appropriate for him to use. But since it's a game, he's eventually going to be wearing armor and fighting with a hammer or some other random weapon so it probably doesn't matter.
