I need to set up the basics of the magic system now.
Magic is the trained art that allows creatures to tap into either the residual enegies left over form the birth of the universe or a God. This can theoretically be taught to almost anyone but doing so is difficult in practice. The broad principles of how magic works can be understood academically but the way each individual taps into magic is just different enough to prevent it from being an absolute science. The personality built into the power tapping means that each magic teacher can generally only have about 1-3 students due to the personalised teaching methods. Depending on the speed of the students and the skill of the teacher making a competent mage takes between 2-8 years.
Just for clarification a Mage taps into residual power while a Cosmurgist/Cleric taps into the power of the Gods. Cosmurgist is the academic name but those who tap into the power of Gods are almost always followers of the deity they tap into for reasons that will be explained hence "Cleric". Becoming a Cosmurgist requires a highly complicated magical ritual known as Divine Union. If it works then the Cosmurgist "Syncs up" with the God, once connected their minds connect on a relatively simple level. The Cosmurgist can request magical effects and can get a general feeling for how much the God likes him/her. The God can send magical effects linked to its aspects through the Cosmurgist, it also gets a general understanding of how much the Cosmurgist likes him/her and his/her current status.
Note that nothing stops someone from being both a Cosmurgist and a Mage, however Divine Union only works with one God at a time.
Inanimate objects can be permanently given a magical power of some kind. This involves bending its magical properties in order to change its magical status, making enchanting items an act of limited reality-warping. This is far more energy-intesive then coaxing out the effect normally but it is permanent and it sticks to the item until it's inscription is wrecked.
Inscriptions are a set of symbols carved into the item which basically hold the altered magical data. Anyone sufficiently can create an Inscription but only a mage can empower it in order for it to take effect.
This should be the third to last worldbuilding post, I have an idea for an adventure aswell! What about rescuing kidnapped royal heirs from a cult?
