Minstrel Web, also known by her stage names of Infinity and Spiral Orb, is a large spider musician that appeared in 3 consecutive Hallowe'en events: 2009, 2010, and 2011, as well as the Gower Quest.
For the 2009 Hallowe'en event, players had to go to the Grim reaper's house and try get this spider out of his bathtub, as if the Grim Reaper touches her, she will die. The Grim Reaper does not want to do this, since "its time has not come" (the spider is far from its death). This isn't as easy as it sounds as players have to go to the Spider Realm to ask the Spider queen to make the spider leave. The spider isn't very talkative which certainly doesn't help when trying to get her out of the bathtub.
In the 2010 event, players had to help her by finding coloured spiders in the Grim Reaper's house then putting them on tiles of corresponding colour to create music. Between the two events, Allan, a raven, flew into the web of Minstrel Web, where she asked it to either help her or get eaten. In the 2011 Hallowe'en event, Minstrel Web was named Infinity.
During the Gower Quest Minstrel Web appears as Spiral Orb, the DJ at the Behind the Scenes bar. During the quest, she informs players on where the missing Life altar fragments are located. After the quest she gets inspiration from the player's actions and composes a song called 'Broken Rocks, Broken Heart'.
The bathtub still shows as an NPC dot on the minimap even after the spider leaves. Also, when you right click on the bathtub, it shows "Bathtub" in yellow, showing it is an NPC.
The spider is featured in a wallpaper sitting in a tub and playing with a duck.
She was the orchestra during the 2010 Hallowe'en event.
Infinity from the 2011 Hallowe'en event is one and the same with Minstrel Web; this is explained in the fact that she simply renamed herself after she split from Adamantite Damsel. On the RuneScape website she was referred to as "Infinity, the artist formerly known as Minstrel Web", a reference to the singer Prince, who once changed his name to "the artist formerly known as Prince" and a symbol.
