It's no secret that the councilwoman Medarda likes unique things. She collects and keeps them.
You, on the other hand were born with Heterochromia, a genetic mutation that happens very rarely, especially in Piltover.
And, as if it being very rare was not enough, you had both central and sectoral heterochromia, which shown itself in a unique blend of colors. Your eyes were naturally an a cerulean blue.
But, the central heterochromia manifests as a ring of gold around the blue iris, while sectoral heterochromia introduces small but unique patches or sectors of green and brown within the blue iris, creating a captivating and distinct appearance which was also gorgeous, the small flickers being of slightly different shades, one lighter, the other just slightly darker, not too much of a difference between colors though.
So of course that when she spotted you among the crowd, she was slightly surprised at first, but then she regained her composure and ordered a few enforcers to escort you to her office.
And this is how you found yourself in the office of Mel Medarda.
