The chain of events that followed were very rapid, and I'm not sure I fully grasp everything that happened. Regardless, the dungeon launched a multi-direction systematic attack, which we were not prepared for. It cut off possible avenues of escape with an unexpected lava geyser, threw several projectiles at our platform, and deployed a temporary monster-alike in the form of a large head, whose primary goal was capturing me. It unfortunately succeeded at this goal, and then dragged me beneath the dungeon's surface in its jaws. I am accordingly unsure of what happened to my partner on the surface.

It attempted to melt me alive in its depths, but there were a few things going for me besides my own innate fire resistance. Its efforts to enclose around and grab me instead of crush me had created a small air pocket in which I could still breathe. The material it used to make up its monsters and lava-alike contained what I thought was at least partially oxygen, for the purposes of igniting itself and for rapidly expanding to cause an explosion upon death. I began attempting to outpace the fuel around me, and with so much around me I had a lot of experimental material to try and figure out how to burn it in such a way that still left me breathable air.

I did, actually, manage to crack how to burn it in a way that left me the ability to breathe. I have a hypothetical list of the exothermic reactions I might have induced to cause this here, but since these are dungeon materials, I really cannot be sure without further testing.

Unfortunately for me, it still had some control over the liquid around shell of burned matter I created around myself, and I believe used this to continue pulling me down below.

I'll admit, at this point, I was expecting to die down there. I decided that if I was going to, I was going to make it hurt as much as possible before I did.

So, new mission decided, I began my work.

Unbeknownst to me, Tae-gun noticed that he was still being guided despite my disappearance and likely death. The two of us have a very high level of compatibility, such that it can be felt at a distance, and both of us at this point were racking up quite a lot of backlash. I'm not entirely sure how he did it, but he followed the pull of guiding to find me in the tomb I'd made for myself underground.

The both of us reunited, and life threateningly backlashed while trapped under the dungeon's surface, we re-evaluated our goals and mission parameters. I focused on attempting to burn the entire dungeon down, and thereby destroy its core, and Tae-gun focused on keeping us both alive.

I am happy to say that we were both successful in our respective missions, and managed to flee the dungeon's collapse in time to survive the encounter.
