Your ability to manipulate Mana, one of the fundamental energies of the multiverse, is unlocked. Your mana core has just formed and starts with a small capacity to store and transfer mana but it can be increased through practice and rituals. You have an innate knowledge of the basic elements of the three fundamental branches of mana manipulation.
Conjuration, the shaping of mana into constructs that produce an effects. More commonly known as spells, your library contains information about many different systems of magic and with perseverance you might discover the secrets of True Magic.
Enchantment, the creation of objects powered by Mana, capable of producing the same effects as Conjuration but anchored to objects.
And Alchemy, the creation and transformation of materials and liquids with Mana. From potions producing effects when ingested to esoteric metals and gems to use in Enchantments, the creation of devices, or armor.
A library of grimoires about the three branches of mana manipulation has been implanted into your memory as well. You will still need to read and understand them and acquire the necessary skills but all the knowledge you need is at your fingertips. With this power, you can reproduce any magic system from first principles and even create your own. The library contains several broad magic systems to get you started.
While this ability has no theoretical upper limit, the more complex and powerful Conjurations will test your knowledge. Over time, as your understanding of mana expands, you can discover new branches of magic beyond the primary three. With enough time you will be able to reach heights only the gods can dream of but be careful not to break reality or destroy your soul on your journey there. You can reach the power of Sorcerer Supreme in around a decade of study and practice. The more time you dedicate yourself to it, the shorter this time becomes.
