How a writer got his dream job making a fantasy book for the nerdworld empire Critical Role

By Eric November 17, 2025

Martin Cahill, a dedicated fantasy writer, has made an impressive leap from fan to collaborator in the vibrant world of Critical Role (CR), a popular Twitch stream known for its engaging Dungeons & Dragons campaigns. As the creative mind behind “The Armory of Heroes,” a lavish 216-page compendium released in July, Cahill has crafted a rich tapestry of lore, artwork, and character insights that celebrate the beloved narratives of the CR universe. The book showcases intricate illustrations of relics, armor, and weapons, all tied to the various campaigns that have captivated audiences for nearly a decade. Cahill’s journey began in 2015 when he first discovered CR, a source of inspiration and joy that ultimately fueled his passion for storytelling and writing.

Cahill’s transition into the role of writer for CR was serendipitous; he was approached by a contact from CR’s publishing arm in August 2023, who sought a writer to contribute to “The Armory of Heroes.” With an initial brief in hand, Cahill proposed a multi-character narrative that would serve as the backbone of the book, allowing for a deeper exploration of the characters and their stories. Throughout the collaboration, he received constructive feedback from CR co-founders and the crew, including a memorable moment when co-founder Liam O’Brien praised Cahill’s depiction of his character, Caleb Widogast, with a simple note of “perfection.” This experience highlighted the delicate balance Cahill maintained between his enthusiasm as a fan and professionalism as a writer, allowing him to contribute meaningfully to the CR legacy.

Cahill’s insights extend beyond his personal journey; he offers valuable advice for aspiring writers looking to break into the publishing industry. He emphasizes the importance of networking and being vocal about one’s aspirations while remaining respectful and helpful to others in the community. Persistence, he asserts, is crucial in an industry often characterized by rejection and challenges. Cahill advocates for the power of follow-up communication and maintaining kindness in all professional interactions. His journey from admirer to collaborator serves as an inspiring testament to the potential for creativity and collaboration within the fantasy genre, encouraging others to pursue their passions while fostering a supportive network of fellow writers and creators.

Speaking to author Martin Cahill feels like looking into a mirror. We both dabble in writing in the fantasy genre: Cahill professionally, I in my downtime. But Cahill has gone a big step further than me: He secured a dream gig creating a book for the nerdworld
empire Critical Role.
Cahill is the wordsmith behind “The Armory of Heroes,” a fantasy compendium CR released in July. The 216-page book features detailed artwork of relics, armor, and weapons from CR’s campaigns, the
long-running Twitch stream
that’s a mainstay of the company’s sprawling business.
Cahill started watching the CR stream in October 2015, some eight months after the crew of eight had first started broadcasting their
“Dungeons & Dragons campaign”
for several hours every Thursday night.
Ten years on, the CR crew
sells out arenas
and has two
Amazon-backed animated series
based on their “D&D” campaigns, and Cahill’s gone from viewer to creative collaborator.
“It just became one of those sources of light and hope,” Cahill said. “And CR also became, at least for me personally, a place where we can escape to and feel some joy and win over bad guys.”
He was also drawn to CR as a property because it was his “favorite kind of storytelling,” and reminded him of the plot threads he’d tried to include in his own writing.
“We get the bitter and the sweet, we celebrate the things that are good and we mourn that which is bad, and we find a way to keep going,” Cahill said.
The dream job
In August 2023, he was approached by a contact working with
CR’s publishing arm
, who was looking to sign a writer that would be a good fit for “The Armory of Heroes.”
Cahill was given a brief to work with. However, he had the latitude to pitch ideas for how the book would flow, and he proposed a multi-character narrative that became the core of this CR encyclopedia.
“The Armory of Heroes” features character art and campaign lore from Critical Role.

After comments from the
CR co-founders
and the crew’s lorekeeper, Dani Carr, and rounds of edits, his section of the book was done, pending illustrations from artist Ana Fedina.
A highlight for Cahill came when he received a note from
CR cofounder Liam O’Brien
on one section of the book dedicated to O’Brien’s campaign character, Caleb Widogast.
“Liam had just written ‘perfection’ next to it. I guess I captured some aspect of Caleb in a nutshell, and I think it was cool to see Liam had liked that and appreciated it,” Cahill said.
Cahill said working with CR also meant he had to keep a clear separation between being a fan and a professional.
“It was both very business as usual and also very, very amazing when you have those moments of connecting with people,” he said. “It is business as much as it is art, and I think part of the process is being able to say: ‘Hey, I’m a huge fan. Now, what do you want me to do with page three?'”
Getting your work in front of the right people
Cahill has worked on and published a hefty stack of science fiction and fantasy works outside his work for Critical Role. This summer, he published his debut fantasy novel, “Audition for the Fox.”
Cahill said there isn’t a one-size-fits-all approach to getting a cool gig in the creative industries, but there are things you can do to get your work in front of decision-makers.
First, it starts with being vocal about what you want to do and broadening your network, while not being pushy about securing opportunities.
“There’s a way to do it that is not like ‘Hey man, introduce me to your cool friend, or we’re not friends.’ There are ways to use your network of friends and creators and be open to helping people right back,” Cahill said. “But in the publishing industry, being OK at becoming comfortable with asking people to introduce you could lead to great opportunities, and conversations about what you’re interested in doing.”
Tip two about networking your way into jobs, Cahill said, is to pay it forward when you have an opportunity that may suit someone, and view it as helping a friend out.
“I don’t see any point in being an obstacle to people, or ‘being better’ than anybody,” Cahill said. “We are all in here to help each other.”
Cahill’s final tip for writers seeking success in publishing is that “persistence is key” in the face of rejection.
“It is an industry that does not love you back. It’s also an industry that does not reward sitting on one’s laurels,” he said.
He is a big fan of the follow-up email and check-ins after two weeks. However, it’s also important to be mindful of a potential collaborator’s time and to be respectful of what they’ve got on their plate.
“Being persistent is good, and so is being kind,” Cahill said.
