Unknown Origin (5e Subclass)
From D&D Wiki
You have no clue where your magical power come from or whom could have given it to you. You might have been born with this magical essence or you have manifested magical abilities during a certain age wether by choice or accident. Nevertheless magical essence is flowing in your veins. The magic can be sometimes weak and some times it can be really potent. You don't really know how it works but you know you have magic and it is a part of you. You have some kind of control but you act on instinct. You might have a mentor guiding you through the difficult phase of your life or you just kept your gift by yourself.
