Priscilla

Priscilla The Spider Queen is an unreleased champion that was left in the development stage by Riot Games, and her artwork and spell icons are present in the game files.

It was rumored that Spider Queen was reworked into, since that was the name used for Spider Queen. Also, in early development Nidalee used poison in all of her attacks and her Prowl caused her to become camouflaged. However, on May 22, 2010, Coronach (Associate Game Designer) stated: "To fuel more speculation, is not Averdrian and  is not the Spider Queen."

She could be based upon the DotA hero "Broodmother" seeing as they are both spiders with similar skill concepts.

On August 19, a sneak preview of was released. While the two share a similar appearance, (Both having arachnid-like legs, the design of which are near identical between the two Champions), it is uncertain as to whether or not their skills would have shared similarities due to a lack of information on The Spider Queen. It is possible that she has been reworked into Urgot, but this has not been confirmed. 

There is a poll on the LoL Forums attempting to bring the Spider Queen into the game here.

, a new item released for Dominion in September 2011, may have a correlation to Priscilla because of the name and the fact that the item grants a higher capture rate and spiders are known to capture enemies, although the item was removed shortly afterwards.

Priscilla has been renamed Elise, the Spider Queen.
