I found a cave, The Spike of Mastering, where it was said a crapload of kobolds had died of hunger not so long ago. Curious as to what kind of a hive it must be, and besides pretty much bored by my recent surface endeavours, I got my stuff together and descended along with my loyal "broad and incredibly muscular" killer-machine miner chicks beside me, singing "We'll smash some kobold skulls today". As I stuffed my backpack with one valuable gem after another, I was getting more and more intrigued.
Then there was this narrow steep passage downwards, where, you know, one of the slopes was seperated from another by a single z-level. So I jumped down, with no real harm on the impact (well, except two legs broken, with fucking bones jammed throught ankles, but hey, that's not what a nap on a cold cavern floor can't heal).
"Nah" I thought, "I'll navigate through it, sure, there must be another entrance" and saved the game.
"You just wait for me in our nest, gals".
And lo, almost a week has passed as my Legendary Hero, the one and only minotaur slayer, the Yearling of fuckng Blocks, got totally lost in a maze of a cavern, gnawing on some tunnel tube occasionally, unshaven, alienated, with god-knows-what infection in his finger. I feel like a couple of days more and he'll just sit there, portray some random face on a fungi and call it Wilson.
