Codex

Codex is a team that participates in the MIT Mystery Hunt. The team was founded in 2002 as an off-site team in Harvard, and hunted onsite starting in 2003. Codex won the 2011 MIT Mystery Hunt and thereafter ran the 2012 hunt. The team generally chooses a different historical codex to name themselves after each year. A group of Codex members additionally ran the QoDE Puzzle Hunt in 2021, and this group also does other online hunts together.

History
In 2004, Codex got an influx of members from ACME, which had disbanded after running their 2003 hunt. The team also has a strong presence in the Wikimedia Foundation, and was one of the first teams to build their own hunting framework website, the Codex Blackboard, which initially had a wiki-like interface and later had managed spreadsheets. The team was also one of the first to bring computers for every hunter. As a result, the team is known for having strong support for remote solving. When Pturnips disbanded in 2007, most remote members joined Codex (with on-site members typically joining Central Services). In 2018, the team split up into two teams as a result of the new soft team cap, Codex Ogg and Codex Vorbis (a play on the audio codec ), though the team remerged the year after.

Team Names
Codex team names are generally historical codices, with some exceptions (such as Ogg and Vorbis in 2018, as well as CDEOX-21 in 2021). The two characters in Codex's 2012 hunt renamed their surnames Bialystock and Bloom (in the musical ) to Borbonicus and Bodley, two additional historical codices. In 2020, the team was named after Codex Argenteus. The team name in the 2022 hunt run by Palindrome, Codex Vindobonensis 751, is notable for including a mysterious (and as of currently unsolved) palindrome, "METROHOCANGISSITISSIGNACOHORTEM".
