From the introduction:
In ancient days, your family held dominion over this world. They were powerful, deadly, and wise. At least, that’s what they tell you. But all you’ve ever seen is empty faith and crumbling dreams. You just want to live your life like any other kid, but they have bigger plans for you.
They say that there will come a day when the serpent rules once more. That once again they will swap secrets with powerful allies and venom with powerful enemies. But they need your help first. After all, what is family for?
This is a playbook or "skin" (character sheet and basic play rules) for the Serpentine character.
