I am sad to say I will disagree with you on this one as a published writer of fantasy and fairy childrens books, I would never associate hell with my imaginative and whimsical creatures. Your characters have love, care and compassion and there is life abundant in your game.
I would associate your creations with the Fey as there is a saying that no life can grow in hell as it's too hot, and there is especially no love, kindness or compassion in hell either that your gentle characters reveal.
I can only hope that I can cause you to ponder my words. It's never wise to make evil good and good evil in life and in creations.
