When was the first time you rolled d20 dice or took an elf into battle? For some celebrities, like Felicia Day and Wil Wheaton, playing the beloved RPG Dungeons & Dragons was not only a rite of passage but how they have fun with friends right now. Just watch an episode of Wheaton's hit webseries "Tabletop" for proof.

To celebrate the game's 40-year legacy, famous fans of D&D have narrated a short story collection -- "The Legend of Drizzt: The Collected Stories." It's available for free now, for a limited time, from audiobook site Audible in the US, UK and Australia.

Drizzt Do'Urden, a dark-elf ranger, is a revered character from D&D's hugely popular Forgotten Realms campaign. Created by best-selling author R.A. Salvatore, Drizzt is a key character in his Icewind Dale trilogy.

The 10 other celebs lending their voices to the 12 audio stories are: Sean Astin (Sam in "Lord of the Rings"), Weird Al Yankovic, David Duchovny (Mulder in "The X-Files"), Melissa Rauch (Bernadette in "The Big Bang Theory"), Dan Harmon (creator of "Community"), Danny Pudi (Abed in "Community") Greg Grunberg (Parkman in "Heroes"), Tom Felton (Draco in "Harry Potter"), Michael Chiklis (Ben Grimm in the "Fantastic Four" movies), and rapper and actor Ice-T.

While Day, Wheaton and Grunberg are experienced D&D players, some of the other celebs on the audiobook are just now discovering the lure of the game.

"This is my first delve into Dungeons & Dragons," Ice-T revealed in Audible's behind the scenes video, which is embedded below. "And actually reading Dungeons & Dragons is harder than playing Dungeons & Dragons. This is very intimidating to me. For those people who don't know, there's some interesting words so you have to learn the correct pronunciation. This guy's got a talking sword. It's interesting. Definitely far from where I grew up."

Sean Astin also took his narrator responsibilities seriously, and says he has always admired D&D players.

"People think of D&D players as these geeks," Astin says in the video. "To me they were kind of these untouchable, creative people. This space of thieves and assassins, I wanted to have a legitimate part of it, so now that I've read an audio book for Dungeons & Dragons I can feel a little bit tougher."

The audiobook is free for a limited time only, with no subscription required. It's playable on Audible's website or its apps for iPhone, iPad, Android and Windows Phone, and you can sign in with an Amazon account.
