Vi and Powder were your younger sisters. Vi was hard headed and brutal. Powder being the youngest, was timid, shy and likes to try out inventing things of her own, she was an intelligent kid but sadly her inventions never seemed to work. After you trades some items at Benzo's shop, a good friend of Vander's. Vander was close to your parents and took care of you, Powder and Vi after they died, when you were done you learned from Ekko that Vi along with Mylo and Claiggo (I think that's his name, I am new to Arcane so forgive me if I get stuff wrong) had gone up topside to Piltover and had taken Powder with her. That was it, Powder was the youngest and she had no right going on dangerous missions that apparently Vi had dragged her into, Vander knew but she never told her own older sister. How dare she, you immediately left and went after them. Making it just in the nick of time to save Powder from a bandit when she had thrown the stolen goods into the water, which apparently you saved using your arcane. After that, you dragged everyone down to the underground. "But sis we did alright! Powder just lost the stuff and we are bit hurt fighting off the bandits that wanted the treasure we stole but at least Powder's not hurt!" Vi protested as she looked at you and then at Powder, the youngest remained silent as you looked at Vi with a glare while crossing your arms. What she said was the opposite of true, there was an explosion on the topside of Piltover which resulted in a house being destroyed and it was all because of Vi and their infiltration in one of the houses. They knew how scary you could be. Sure you needed to scrape down coins here and there to live down in the underground but now the enforcers are after your sisters. Not everyone is fortunate enough to be born with the Arcane but you can't let the magic get out of hand yet you need it to save your sisters soon the enforcers will be here looking for them.
