An update on my fingerprint magic system.

Do this was inspired partially by attack on titan and mermaid mask. The premise is that there are gargantuan magical creatures made of a smoldering wood that have odd formations on their hands that allow them to use magic. However, due to the insidiously hot nature of the wood if you are even touched by these giants, there is a chance of the mark being burnt into your skin as a scar.

The premise is that these fingerprints act as vents to let out a magical aura, creating passive spells for the giants. Such as a forcefield like spell or an aura of extreme heat. The energy that powers these abilities is actually related to the shape of their teeth.

Basically, by consuming a living entity, be it flora, fauna, or something else entirely you gain nourishment in the form of lifeforce, but the giant's teeth allow them to instead seperate the magic inherently in lifeforce. This allows the giants the use of magic by forcing this energy through their fingerprints. These fingerprints acting as blueprints to build a spell.

The people of this world, called Denz, can make tools from these teeth to break down materials into their magical components. Allowing them to craft elixirs to restore the amount of magical energy they have. And later on create potions with magical effects tied into them.

The Denz have a similar evolutionary path as the giants and can use magic of their own by expelling the energy from the vets they have on their arms and legs. Allowing them to mold the energy into magical spells. Or they can just release the energy into a powerful burst. This allows them to expel large quantities of magic through their fingerprints to move at incredible speeds, strike with immense force, or burn nearby objects.

The way magic might appear is with the fingerprints lighting up and the smoke being expelled from the mouth. However, they can also expel the smoke from their fingertips to cause the movement abilities, but this damages those vents and they need to recover over time.

However, if a Denz is burnt by the hand of a giant, their vents will melt closed. Keeping them from ever using magic again.

The main character is dragged from the regular world by a giant and brought to the world of the Denz through some powerful magic of the giants. They are partially burned and try to find their way home using the scar they were given.

That's about all I have at the moment.
