Request for sheet music!

Hello League of Legends forums,

This is my first time posting here and it's to seek some help! Recently i sent in a support ticket for a request for the sheet music of "Orb of Winter" from there "Pentakill" album and just to show my appreciation for their work for the music they create. You can check out the ticket here for all the details but basically I'm a musician who loves to learn from ear then go online to see how close i am to the real thing. I do this so I don't have to depend on notes to play the music i want, just know them off by heart.

TL;DR: I would love to know who the composer or person behind League of Legends beautiful orchestral music and i couldn't find it online and would love to know if there is any way to see the sheet music for "Orb of Winter" from Riot's "Pentakill" album.
