The Unspeakable Vault (of Doom) or Weird Tales from the Old Ones is a webcomic by François Launet, which chronicles the "daily" lives of the Great Old Ones, including Cthulhu, Nyarlathotep, and Yog-Sothoth, among others. It takes a lighthearted view of H. P. Lovecraft's Cthulhu Mythos to inspire laughter rather than the more usual soul-blasting horror. The comic was used as the basis of the second expansion set to the Cthulhu Mythos themed version of Steve Jackson Games' card game Munchkin.
The webcomic's name is often shortened to UVoD.
In 2003 the Essen Game Fair in Germany, the author, who was there signing books for the Pegasus Spiele game publisher (as illustrator of the German Call of Cthulhu RPG), witnessed the craziness about Cthulhu plushes, sold on different booths: many old players of the Call of Cthulhu role-playing games wanted to buy this icon of the Lovecraftian Mythos. On the train that took him back to Paris, he started drawing the first funny Cthulhoo and Nyarly draft, along with a few layout of strips. Characters were designed in a very cartoonish style, with simplified features and layout, that contrast strongly with the author's illustrations style, more realistic and classical.
