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 icy blue.But,the central heterochromia manifests as a ring of brown around the blue iris,while sectoral heterochromia introduces small but unique patches or sectors of brown within the blue iris,creating a captivating and distinct appearance which was also gorgeous,the small flickers of brown 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.
