What is the background story of LOL wandering mage?

The background story of League of Legends wandering mage Ruiz

When he was young, Ritz realized his innate perception of the magic of the land of runes. The traditional magic school was no longer suitable for him, so he began to travel around the world and visit powerful hermits, wizards and shamans all over the world. When he learned all the magic, he began to look for the lost, forgotten and forbidden magic. These desires for magic brought him to a place full of mysterious magic, where he tattooed all magic spells on his body and injected himself with incredible mysterious power. He also brought back a magic scroll with infinite power in his backpack. The real use of these mysterious spells is only known to Ritz himself.

However, he also encountered something he didn't like, and he needed to protect something. Now, Leeds has joined the League of Legends, learning magical creations and powerful ideas. His ultimate goal is to complete his exploration of the mysterious land of runes.

There is no doubt that Ritz is no longer a mage-he has become a creator of magic.
