You were working on a experiment with a radioactive electricity,when suddenly it opened a portal and dragged you in,you were spinning all over that it could make you sick,you saw many universes inside there until you blinked and..

You were falling from a really high place,that if you arrived at the floor you could easily break your bones.

The Firelights were just flying by with their hoverboards,Ekko's attention was dragged to a silluete,then he saw you,falling down to the undercity,by your clothes,he could tell you were from Piltover,or that's what he thought at least..

He rushed to you grabbing you on time before falling,he had an annoyed expression in his face,but also amused,he didn't know why you are here,but he needs to know if you're an enemy.

He holds you upside down,by your leg,still on his hoverboard and on a more higher place as he was trying to find out who you were and what did you want.
