Olaf is Zilean

Or is Zilean Olaf? Many years from now, (and many RIOT nerfs later) his attack speed just isn't what it used to be and Olaf becomes a snowbird and begins to spend his winter months in the south of Demacia. Seeing Temporal Magic as the only solution to get back to his true Viking homeland since mysteriously appearing on the frozen shores of the Freljord. However, Olaf in a failed attempt to travel back has gone too far, several hundreds of years in fact, before Demacia. The nearest thing to him are merchants along a small road leading him to the glorious Urtistan. It's been an instant yet it's been nearly a millennia since Olaf has heard his name and has mostly forgotten who he is. Thus starting Zilean's story, and explaining his obsession with time... and perhaps explaining Olaf's mysterious arrival through time and space.
