The Violet Banquet

read it on AO3 at https://archiveofourown.org/works/84103841 by viridVerdancy The Violet Banquet (TVB) is the name for the main group RP event in which alternates from across UTDR multiverses are invited to an estate party. The prototype (TVB 0) ran in February 2025 on the anniversary of Muffet's Love Ball, and the first canon event was held February 2026, starting at midnight EST on the 14th and ending at midnight on the 23rd. The special lore unlocked by special side-quests are exclusive to the namesake events hosted on the estate itself by Ridwan, but there are also mini-events throughout the year hosted off-site by the other staff. As of yet, the main events are annual, but they are available for backreading year-round to those in the Discord server (linked to in the pinned post on @thevioletbanquetutmvrp on Tumblr) with the archive role 🔑. This is an adaptation selectively transcribed from the chat logs for audience accessibility, edited for formal syntax and narrated wherever context provided by chat or channel descriptions needed to be readded.
