C’thun spends a creation act to alter the newly created magic systems with drawbacks and incentives, all spells are innately complicated and require learning to properly use, with rituals and gestures being required depending on the power of the spell.
If incorrectly cast, the caster in question gets corrupted and suffers a mental drawback, suffering major headaches. If they miscast another time, C’thun gets ownership over their soul. This is used as a way to make sure people only cast spells they are absolutely sure they can.
(Do we have any sentient creatures yet?)
Harvey Harvest rolls his eyes and mimes planting a metaphorical fruit, creating the Anti-Corruption
Anti-Corruption
For anyone whose soul belongs to C'thun (including disembodied souls), if they perform the following actions ownership of their soul will transfer to the following entities. The following actions will also clear any mental influence related to C'thun. This will do nothing for those who do not owe their soul to C'thun. If a soul is not owned by C'thun but does have C'thun's mental influence, it will clear the mental influence without transferring the soul. It is only fair that we get a way to steal followers
back. Soul ownership may change as normal after the switch is made.

If a Soul revels in its Corruption and enjoys being under C'thun's influence, then the Anti-Corruption will have no effect and the soul will permanently belong to C'thun even if other actions are performed that would normally transfer their soul to another god. Any non-mundane attempt by C'thun to compel the corrupted to be happy will not count and will instead give ownership of the Soul to the mortal (as this is assumed to make them happy).
