So, a bit similar to the situation outlined in /posts/2934809: very early in Arknights' promotional cycle, NoriZC produced a few pieces of art and made comments alongside side them that gave the true name of Silence (then Silent) as Olivia Hermer. In the game as published, she gives her name as Olivia Silence. It would appear that the "Hermer" surname is another element that ended up on the cutting room floor. The tags here are intact (since NoriZC cited them) but in the future, unless Nori or another artist directly cites the name, post-launch Silence art should simply be tagged "silence_(arknights)".
