The Halls of Agemmon was a dungeon found underneath Villagetown in Tunnel 67, which was previously blocked. It appeared during Nether Kitten 6.
This dungeon was once a high dwarf area, an ancient structure. Therefore, the mobs do not respawn.
Diary of an 8-bit
Runt mentions that some miners mined into a giant room made of gold and copper. They are excited until they here a deep hissing. They run out and block the entrance with 6 layers of cobblestone and a fence, as well as naming it Tunnel 67 and putting a bunch of signs telling people to keep out.
Tales of an 8-bit Kitten: A Call to Arms/Nether Kitten 6
Eeebs chases a pigman mage only to find he went into Tunnel 67. He goes in and finds out that Tunnel 67 is in fact a dungeon. He found Glorm dueling Bayliss, and fought alongside Glorm, who fought and defeated Bayliss, however, they failed to stop Bayliss and the rest of Nova's followers from completing a ritual that would awaken all the monsters in a certain radius.
At first, only the Red Wyrm, the Final Guardian, appeared. Eeebs, Glorm, and Lyra were able to hold it off until The Lost Legion arrived. Using his wish token, Hurion summoned Nelmi and a Kaiju. At first, it seemed like the Kaiju had the upper hand.
Then, a large number of mummies, ice golems, crypt slimes, zombie trolls, and a Lurker arrived. While the Kaiju and The Lost Legion focused on the new mobs, Glorm and Eeebs tanked the Red Wyrm. Nelmi later joined in after saving Eeebs from the Crypt Slimes, blasting the monsters with a high-level Fire Cube spell.
The loot was a huge ton of XP, a few hundred dragon scales, a shard of Critbringer, pocket stables, and dragon affinity (one requirement for dragon related classes) for all participants.
