For the5th edition ofDungeons & Dragons, Baker was the lead designer ofWayfinder's Guide to Eberron (July 2018) which was an official Wizards of the Coast supplement published as a PDF on theDungeon Masters Guild.[28][29] The Dungeon Masters Guild, owned byOneBookShelf, 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 onDungeons & Dragons intellectual property".[30] Utilizing the Dungeon Masters Guild, Baker then published two non-official Eberron themed adventures in 2018 and a non-official 5th edition Eberron supplement in 2019.[31][32][33]
Baker was also one of the lead designers of the first hardcover 5th edition Eberron sourcebook,Eberron: Rising from the Last War (November 2019).[34] 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),[35][36][37] and a supplement,Eberron Confidential (November 2020).[38][39] 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 andcodenamedProject: Fool's Platinum.[40][41][42] In November 2022, Baker announced thatFrontiers of Eberron: Threshold had been delayed due to theCOVID-19 pandemic and was now scheduled for release in 2023. However, the release ofChronicles of Eberron (2022) was not delayed and was published in December 2022.[43][44][45]
In January 2023, Baker wrote that he was considering a shift away from creating third-party Eberron products and instead concentrating on expanding aspects ofThreshold that are unconnected to Eberron's fictional canon, allowing him to release it as his ownintellectual property.[46][47] In June 2023, Baker announced that his third-party Eberron publishing imprint KB Presents would be shutting down and Visionary Production and Design would take over the stewardship of the Eberron products published on the Dungeon Masters Guild. As part of this handover, a final Eberron product –Frontiers of Eberron: Quickstone – was also announced;[46][48] thePlayer's Handbook (2024) compatible sourcebook was released in September 2024.[49]
In 2014, Baker co-founded a new an indie tabletop game studio with his wife, Jennifer Ellis.[50][2] In April 2015, Twogether Studios launched their first game,Phoenix: Dawn Command, onKickstarter[51] and raised $67,284.[52]Phoenix: Dawn Command is a card-based roleplaying game where players become "more powerful each time they fall in battle".[53]
In October 2016, Twogether Studios launched their second game,Illimat,[2] on Kickstarter[54] and raised $418,628.[55] This set collection game was designed in partnership with the bandThe Decemberists and illustrated by Carson Ellis. Steve Haske, forInverse, wrote: "Last year, the band’sChris Funk got in touch with Portland-based Twogether Studios, in order to bringIllimat 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".[56]
Twogether Studios has launched two more successfully funded card games on Kickstarter:Action Cats! (July 2017, raised $17,086) andAction Pups! (February 2019, raised $7,273). Both games feature photos of pets that Kickstarter backers submitted.[57][58]
In September 2019, it was announced that Twogether Studios was working with the McElroy family to create a cooperative storytelling card game adaptation ofThe Adventure Zone calledTAZ: Bureau of Balance.[59][60] After its release in 2020,CBR called it "a great way to bring the joy ofThe Adventure Zone to the table and get in on the action".[61]Io9 highlighted that it "is a great card game for folks wanting to try out (or get back into) RPGs, or more seasoned players who want a cooperative storytelling experience that takes out some of the legwork and guesswork for an afternoon. It’s not going to give you all the thrills and chills of a traditional RPG, but it does enough to simulate the experience".[62] In 2020, Twogether Studios worked with Podium Audio to release theAscend Online Roleplaying Game, "a micro roleplaying game", based on the audiobook series of the same name by author Luke Chmilenko.[63]Io9 reported that "Ascend Online is about a group of friends who’ve gotten more than they bargained for in an immersive fantasy video game" and that it is "a mix betweenReady Player One andSword Art Online"; the free "micro RPG lets players create a party and explore the series’ world, creating their own collaborative adventure along the way".[63]
In July 2025,Darrington Press announced that Baker and Ellis are creating a "new world" with player options for the tabletop role-playing gameDaggerheart.[64]
