Needle Knight Leda, is a character in Elden Ring: Shadow of the Erdtree. She is a follower of Miquella, and the character you meet in order to access the expansion.
While she never removes her helmet in-game, official artwork of her without her helmet was released, showing she has blonde hair tied with a braid. Her face has since been compared to Saber from the Fate franchise.
Despite the cordial and friendly impressions she initially gives, it is revealed to be a facade once Miquella's charm is broken. Beneath her image of an ideal knight, she is highly zealous and viciously paranoid, eager to hunt her fellow seekers on the suspicion of disloyalty to Miquella.
