Old School RuneScape uses the British convention for floor numbering: Ground floor, first floor, etc.
Valaine is the owner of Valaine's Shop of Champions on the 1st floor[?] of the Champions' Guild.
She runs a general store, allowing players to sell anything to her. She sells blue capes, black full helms, black platelegs, and adamant platebodies. It is not recommended to sell items to her as she is far away from a bank, although players may occasionally sell raw chickens from the coop downstairs, redberries from the bush plot nearby, or rope and assorted drops from the nearby mugger.
