Magic System

Magic in Ofadin comes from mystical pools of syrup like liquid that seeped into the world's nooks and crannies, almost in all cases found in the enormous cavern systems deep underneath even dwarven cities, hailing from magical disasters or leaks from the afterlife.
This syrup, henceforth known as Mucena, has a very strong mint like flavour, though it is not pleasant to consume. The ritual for one to consume Mucena involves three attendees, other than the aspiring sorcerer, armed with flexible rods that bear a resemblance to honey dippers - their job being to push all of the Mucena into the sorcerer's throat. If even a drop spills it could have disastrous effects (not only for what it touches -with Mucena being highly corrosive- but it will cause a disconnect from the syrup in the body and the one that spilled - tearing the individuals body as if a magnet tearing through them from inside, violently pushing toward the drop). As you can imagine this process is extremely painful.
If the sorcerer can withstand the pain and power through their body and mind violently rejecting the substance they enter a binding process with the Mucena.
Their ideals, passions and deepest desires, which it uses to conduct a form of metamorphosis. It integrates with their spine and nervous system, replacing nerves with a series of microscopic vein-like tubes that transport the Mucena from brain to all parts touched by the bygone nervous system. It is the aforementioned personality traits of the sorcerer that define the magic type the Mucena will give them.
Mucena cannot change the magic type during the sorcerer's life, but it can fade with substantial mental damage. Sorcerer kills are often done by significant damage to the head and neck in order to sever the caster's mental function before their bodily one; doing the opposite would result in Mucena commencing an event known as "mourning", where it lashes out and manifests into abominations of ages old, powered by the raw emotion and sorrow of never being able to fulfil their bounded sorcerer's passions and goals.
