First born

You were the firstborn child of a great lord, gifted to a witch or devil so that your family could attain power before you were born. Through this, you have gained the ability to use magic placed within you by this entity. These spells are cantrips, three chosen from either the bard, druid, sorcerer, or warlock spell list. They can all come from the same, or different spell lists,  and your spell casting ability for these spells depends on which spell list they come from e.g. charisma for Bard, Sorcerer, and Warlock or wisdom for Druid.
