Short answers, pulled from the story.
The Dungeons & Dragons animated series followed six children, aged eight to fifteen, who were transported to a fantasy realm after riding an amusement park roller coaster. A guide called the Dungeon Master gave each child a magical weapon keyed to a character class, and they spent the series trying to find a way home while battling the evil wizard Venger.
The Dungeons & Dragons animated series aired on CBS from 1983 through 1985. It ran for three seasons and twenty-seven episodes total, co-produced by Marvel Productions and TSR with animation by Japanese studio Toei Animation.
The episode 'The Dragon's Graveyard' nearly faced cancellation because the characters seriously contemplated killing the villain Venger. American broadcasters considered the premise too violent for a children's show. In 1985, the National Coalition on Television Violence separately demanded the FTC require a broadcast warning, claiming the series had been linked to real-life violent deaths.
'Requiem' was a planned final episode of the Dungeons & Dragons animated series, written by Michael Reaves, that was never produced due to the show's cancellation. It would have confirmed that Venger was the Dungeon Master's corrupted son, redeemed Venger, and offered the children a path home. Reaves later published the original script on his personal website, and BCI Eclipse included a recorded audio drama version as a special feature on their DVD release.
Venger was voiced by Peter Cullen in the Dungeons & Dragons animated series. Shadow Demon was voiced by Bob Holt, Tiamat and Uni by Frank Welker, Kareena by Diane Pershing, and the Dungeon Master by Sidney Miller.
