The magic came from the sun as the Sun is technically a primordial god's eye or head. Still contemplating that.
There are two types of Sun users.
Sun Wielders, People who could use sunlight as long as they are in the gaze of the sun.
Sun Children, People who could use sunlight without the aid of the sun as they develop their own core to generate sunlight.
Most things need sunlight but getting too much would cause damage. The limitation is how much people can handle it.
People can develop a form of resistance but never immunity, no one can develop an immunity to the love of an eldritch horror.
The sun loves and hates too much, so can you handle this intense feelings of the sun towards you?
Seers, They mostly use their eyes or head, in general, to see the possible futures that could happen. However, the more they look, the higher the side effects, such as dizziness, headache, temporary blindness, and fainting <- These are the milder consequences if Seers continued to abuse or get greedy with their powers then it would cause brain damage, amnesia, permanent blindness, and even death if the brain gets overloaded enough.
Weapon Conjurer, the ability to mold and shape sunlight into weapons that can do some very serious damage to people. However, weapon conjurers burned their hands or worse, they lose their arms. A couple of the side effects are losing your sense of touch, having a difficult time moving your fingers, and possibility of burning your hands until it is bones.
Regeneration, Uses sunlight to heighten an average person regenerative properties. However, this could be very dangerous if you're not careful enough, such developing a cancerous mutation, exploding the said injury limb, or just generally burning it again.
