was an official Wizards of the Coast supplement published as a PDF on the Dungeon Masters Guild. The Dungeon Masters Guild, owned by OneBookShelf, is an online store that hosts official Wizards of the Coast products and acts as "a platform for players to publish lore, maps, character designs and adventures based on Dungeons & Dragons intellectual property". Utilizing the Dungeon Masters Guild, Baker published two non-official Eberron themed adventures in 2018 and a non-official 5th edition Eberron supplement in 2019. Baker was also one of the lead designers of the first hardcover 5th edition Eberron sourcebook: Eberron: Rising From The Last War (November 2019). In the following year, Baker released two new non-official 5th Edition Eberron products on the Dungeon Masters Guild: a campaign guide, Exploring Eberron (July 2020), and a supplement, Eberron Confidential (November 2020). In December 2020, Baker announced two upcoming Eberron projects which would also be released on the Dungeon Masters Guild in 2022: Frontiers of Eberron: Threshold and codenamed Project: Fool’s Platinum. In November 2022, Baker announced that Frontiers of Eberron: Threshold had been delayed due to the COVID-19 pandemic and was now scheduled for release in 2023. However, the release of Chronicles of Eberron (2022) was not delayed and was published in December 2022. Twogether Studios In 2014, Baker co-founded a new an indie tabletop game studio with his wife, Jennifer Ellis. In April 2015, Twogether Studios launched their first game, Phoenix: Dawn Command, on Kickstarter and raised $67,284. Phoenix: Dawn Command is a card-based roleplaying game where players become "more powerful each time they fall in battle". In October 2016, Twogether Studios launched their second game, Illimat, on Kickstarter and raised $418,628. This set collection game was designed in partnership with the band The Decemberists and illustrated by Carson Ellis. Steve Haske, for Inverse, wrote: "Last year, the band’s Chris Funk got in touch with Portland-based Twogether Studios, in order to bring Illimat into the real world via a Kickstarter campaign. With game designer Keith Baker (co-founder of Twogether), the two designed a relatively simple game played with cards, a few tokens, and a rotating box — the Illimat itself, that changes the 'seasons' of the gameplay — so appropriate to The Decemberists’s old-world aesthetic that it has a fascinating sense of authenticity". Twogether Studios has launched two more successfully funded card games on Kickstarter: Action Cats! (July 2017, raised $17,086) and Action
