Menowin is the curator and host of the Spring Fayre, a circus-like celebration that took place in the Lumbridge Crater. He also hosted the pre-event Build-A-Fayre.
During Build-A-Fayre, players could speak to him to see the event's progress, buy tools for loyalty points, and receive rewards.
As part of the Spring Fayre, he was located on the stage to the north of the Helter Skelter activity. The rewards chest for the pre-event was also located in front of the stage. He could give information regarding the fayre activities.
According to Menowin, he was born in a desert and had been travelling his whole life. His mother ran a mobile theatre, similar to the Fayre he had set up himself. He seemed to have difficulty staying in one place for long periods of time, claiming that "wanderlust" got to him easily.
