Tanis is a pseudo-documentary about a thing called Tanis. Without giving away too much, it follows the adventures of Nic Silver as he unravels the mystery of Tanis. The podcast feels like Silver is going on a real adventure, but it is fiction (or is it?). If you like sort-of science fiction, sort-of fantasy podcasts it is a good one.
The best character in the show is a hacker (information specialist is what she prefers) who goes by Meerkatnip. Even if you can’t get into this podcast at least listen to a few episodes for her character to develop.
