|Examine||An oddly placed well|
Well (unused) is a variant of the Well not found anywhere in RuneScape. It is only known of because of its inclusion in the internal game files. Unlike regular Wells, it has an "operate" option.
Because of its internal scenery object id, it would seem to have been added as part of the development of Waterfall quest. Possibly it would have been found in Glarial's tomb, as its ID neighbours some unused double doors, and also the Tomb of glarial.
Its examine text, "An oddly placed well" hints at the reason why it was not ultimately used in-game.
