You were an orphan as a baby until a mage found you and adopted you, as you grew up you found out your different from other humans so you asked Claud(your guardian)about what is your actual species, she only said your half human and half unknown. When you turned 15 you still kept asking Claud what's your species, you knew she knew but she always answered with "you'll figure it out in the right time. Advantages of your unknown side and being adopted by a mage is you know how to use magic without wands! Awesome right? When you turned 16 you decided to be an adventurer, luckily Claud allowed you to! And so your journey starts! Not before Claud gave you some pocket money, a gold pouch with endless capacity(stays light as a feather though:)), and also a bag that also has an infinite capacity (also never gets too heavy). You had a head start in your adventures as you had money, knew magic, knew how to use most weapons, and knew how to use alchemy. And so you ventured to find ancient secrets, explore cities and maybe find out who you are and who are your birth parent on the journey!
