Dungeons & Dragons Fan Expo London 2026: Cast, Dates & Tickets

Dungeons & Dragons is getting its very own fan expo, and it’s going big. Wizards of the Coast has partnered with AEG Presents to bring a two-day D&D celebration to The O2 Arena in London on 21-22 August 2026, and if that line-up is anything to go by, this could be one of the most exciting tabletop events the UK has ever seen.

The Short Version

Friday 21 August kicks off at Indigo at The O2 with a live one-shot from High Rollers, the UK’s biggest actual play group who are currently celebrating their tenth anniversary. Then on Saturday 22 August, the main O2 Arena, yes, the full 20,000-capacity arena, hosts a live actual play spectacular featuring an absolute dream team of voice actors and D&D performers.

Tickets go on general sale Friday 6 March at 10am via dndfanexpo.com. There’s a presale for AEG Presents newsletter subscribers from 10am on Wednesday 4 March, and a venue presale through The O2 on Thursday 5 March at 10am.

That Cast Though

Right, let’s talk about who’s actually playing on that Saturday night. Jasmine Bhullar, known as ThatBronzeGirl, is running the game as Dungeon Master. If you know, you know. She’s the DM behind Dimension 20‘s Coffin Run, the creator of DesiQuest, and has written and performed for Critical Role and Acquisitions Incorporated. She’s one of the most versatile DMs working in actual play right now.

Sitting around the table? Four members of the Baldur’s Gate 3 cast: Neil Newbon (Astarion), Samantha Béart (Karlach), Devora Wilde (Lae’zel), and Theo Solomon (Wyll). That’s four of the six origin companions from one of the biggest RPGs ever made, all playing D&D together on stage. If you’ve ever wanted to see the people behind those characters improvise their way through a live campaign, this is your shot.

Rounding out the party are Anjali Bhimani (Symmetra in Overwatch, plus she’s a frequent presence on Critical Role and is actually part of the DesiQuest cast alongside Bhullar) and Jasper Cartwright, co-founder of the award-winning 3 Black Halflings podcast and a Dimension 20 alumnus through Rotating Heroes and Oaths & Empires.

High Rollers’ Big Anniversary Moment

High Rollers hit their tenth anniversary in January 2026, which makes this August show a continuation of what’s been a massive year for the group. DM Mark Hulmes and the crew, Kim Richards, Chris Trott, Katie Morrison, Rhiannon Gower, and Tom Hazell, have been running their current campaign, Altheya: The Dragon Empire, and are also in the middle of a Kickstarter for the Altheya campaign setting sourcebook.

The official expo site specifically says they’ll be bringing the world of Altheya to the Indigo stage, so expect a one-shot set in their homebrew world rather than an off-the-shelf adventure. For High Rollers fans, that’s a big deal.

What Else Is Happening?

Beyond the headline shows, both days will feature panels and Q&A sessions with creators and performers, gaming tables where you can actually sit down and play, traders from across the D&D ecosystem, and cosplay meetups. The organisers have promised more announcements before August, including meet-and-greet and photo op add-ons.

It’s worth noting that Friday’s High Rollers show requires a separate ticket from the main Saturday event, though VIP upgrades are available. Saturday’s main event ticket gets you access to all the daytime activities plus the evening arena show.

Easter Egg Watch

The cast list is absolutely stacked with Baldur’s Gate 3 connections, but there’s one notable absence: we’ve got Astarion, Karlach, Lae’zel, and Wyll represented, but no Shadowheart (Jennifer English) and no Gale (Tim Downie). The press release does say “more announcements to follow.” So it will be interesting to see how this unfolds.

And keep an eye on the staging. The press release mentions “bespoke staging designed to immerse fans directly into the campaign.” For a venue the size of The O2, that could mean some seriously ambitious set design. The production values could be something we’ve never seen from a live D&D event before.

Also: this is being billed as the “first ever official D&D fan expo.” The word “first” is doing a lot of heavy lifting there. If this goes well, expect it to become an annual event, and potentially expand to other cities.

Why This Actually Matters

D&D being played live in the main O2 Arena is a genuine milestone for tabletop gaming in the UK. This isn’t a side room at a comic convention. This is the same venue that hosts Beyoncé and the NBA. The fact that an actual play show can headline that space says something real about where tabletop gaming sits in the culture right now.

Whether you’re a seasoned player who’s been rolling dice since the THAC0 days or you got into D&D because of Baldur’s Gate 3 or Stranger Things, this feels like the kind of event that’s worth paying attention to.

Tickets go on sale Friday 6 March at 10am. We’d suggest signing up for the AEG Presents presale if you want the best chance of getting in.
