Silco was one of the most important characters in Arcane, both to Jinx and to the entire undercity beneath Piltover. Out of the entire cast of Arcane, few characters have had more of a direct effect on the show than Silco. Prior to the events of Arcane season 1, Silco had considered himself Vander’s brother, and the two led a doomed revolution against Piltover that ended with Vander betraying Silco. Silco continued his plan to secure the undercity’s independence, this time going directly against Vander. Silco managed to kill his brother, and in the aftermath of their battle, he took Powder in as his own daughter.
