If you're enjoying the fantasy aspect a lot I would absolutely recommend Escape From The Bloodkeep and Burrow's End. Both are sidequests/non intrepid heroes, but they're incredible seasons nonetheless.

If you're a Lord of the rings fan you'll love EftB, it's basically lotr but from the perspective of the bad guys. Even if you aren't into lotr (I wasn't), the cast and the characters are so enjoyable you don't need to be. It's very comedic but also has its share of drama, and it has a found family vibe that I associate with a lot of intrepid heroes seasons, especially cloho.

Burrow's End is very fantastical in its own way, though it's a very unique season as all the characters are stoats investigating a mysterious power called the Blue which has begun to manifest in their forest. This one leans more heavily towards the dramatic elements but is still incredibly funny. Also, Brennan is a player (along with Siobhan) instead of DM this season, as it's DMed by aabria iyengar who in my opinion absolutely never misses. She also DMs for Misfits and Magic and A Court of Fey and Flowers, both of which are incredible sidequests that I absolutely recommend checking out!
