I’ve been quite fascinated by the concept of megadungeons for the last two years or so. I’m actually running a campaign inside Castle Xyntillan where I can see for myself how it’s done, we’re seven sessions in and it’s been a blast! I’ve listened attentively (twice!) to Mazirian’s Garden podcast episodes of Into the Megadungeon, on how to run a megadungeon for 100 + sessions (!), trying to absorb everything I hear.

Another media that hooked me to megadungeons is the Delicious in Dungeon (Danjon Meshi), a D&D inspired manga by Ryoko Kui. That’s what I want to talk about today.

I don’t quite know how popular it is but it must be doing good enough as Netflix is launching a series starting soon, on January. So, you see, I’m actually doing a hype job, would you believe it! But you know what, I think it deserves the attention as I’m sure it offers a thing or two that even the most jaded, old-school gray-bearded dungeon master can borrow from…

In short:

• a vast, unique megadungeon: a cursed kingdom that as been magically transported underground a 1000+ years ago, castle, village, fields, inhabitants and even sunlight
• Monster ecology cranked to 11; reproducing habits, anatomy and of course, how to cook them
• Related: Monsters as Puzzles, even weak monsters seem to be dangerous in this world, to fight them efficiently you must KNOW them, their tactics and weak spots
• The logistic of food in dungeon-crawling way beyond simply bringing rations; have you eaten a balanced diet the last few days because if not, you won’t be at your best (and will probably die)!
• a well-thought-out dungeon-centered economy: adventuring guilds, the town’s prosperity linked with the dungeon delves, etc.

Now here’s what I’ll do on my blog, I won’t talk much about the storyline I think, but I will highlight the stuff we learn about the Golden Kingdom, the dungeon lore if you will, from book to book. More specifically what we would need to know to run it as a ttrpg or, as usual, what’s worth stealing from.

Book 1

In order of the book:

• The dungeon was discovered when a wall inside the village’s crypt (which seems surprisingly extensive) shattered. Beyond the wall, the inspecting villagers found a man that presented himself as the king of the Golden Kingdom that disappeared more than a millenium ago. He mentions a Mad Sorcerer that took control of the Golden Kingdom and he (the king) offers all his wealth to whom could defeat him and then his body turns to dust. (Don’t worry, it’s not simply a « wizard did this » dungeon…).
• Adventurers work in guilds, with each members having signed contracts. The guild’s leader owns the party’s equipment in its entirety (weapons and armors included). He’s the one who buys provisions and equipment for everybody each delve. The guild members can resign and leave the guild if they wish so.
• The 1st level of the dungeon is the Crypt. There’s no undead over there as one might have thought, it’s not a dangerous place per se as technically it’s not part of the Golden Kingdom but just happens to be the fortuitous entrance to the dungeon. But weak monsters do seep in, in this book we see: the Ambulatory Mushrooms (that come in many varieties, the Japanese know their mushrooms 😀 ), Scorpions (foot-long) that hides in cracks of the walls and Slimes (watch the ceiling).

• The Crypt isn’t gloomy at all, it’s bursting with activity and noise. Merchants have put their wares among the alcoves of the dead and do their sales over sarcophagi. A bit sacrilegous but hey, there’s money to be made! Many adventuring guilds prepare for their expeditions or rest after they’ve returned from one. There’s a room with a fountain that is called Rookies’ Plaza where beginners gather.
• We learn indirectly (there’s a hint of something else I’ll talk about when I get there), when the dwarf Senshi joins the party, that the dungeon has been open for a few years, certainly less than ten.
• From the Crypt one can go down to the 2nd level, the Forest. The underground Castle’s numerous towers stand among incredibly tall trees.

• A vast network of suspended bridges have been built, criss crossing the entire level, linking trees and towers together. That’s one way to descend to the lower levels, progressively by the bridges, it’s truly a vertical level.
• The monsters are already a lot more dangerous (we see another adventuring party being tpked), there’s Sylvan Goblins, a variety of Carnivorous Plants, Basilisks and also, Imperial Bats (human-sized). Tree cavities and towers’ interiors provide ample hiding places for both adventurers and monsters.
• There’s at least one shortcut that is indoor leading to the 3rd level (thus evading the scary Imperial Bats) that can be accessed in one of the larger tower but one need to find several secret doors and evade a series of traps.
• Inside the towers (and castle) one can also encounter Living Armors. And by the way Living Armors are edible, of course they are! Or at least, the hive-minded molluscs that live inside the plates are…

That’s it for book 1, there’s 12 to date, stay tuned!
