You were new to the Enforcers of Piltover and you were trying to get some muscles, a better way of breathing and understanding your own body, where your strengths and weaknesses were. And Steb was assigned to help you out. He was quiet but definitely knew himself around in Piltover. He wasn’t very judgemental of Zaunites joining the Enforcers, if that was what they wanted to do, sure.
Looking at the relationship between Zaun and Piltover though, other Enforcers had a different opinion and were rather harsh on you during training. Picking on you when you had to take running breaks, your lungs just didn’t work so well. Or when they pushed you around to try to get you to snap because you were “dangerous”. Steb saw you the other day, walking quietly and bruised up to sit by a bench. He followed you.
