Hm... I could do that. I'm devising an airlock system before proceeding into hell though. Okay then, I have an objective for all those poor, unemployed miners. Fantastic.
The following was found on an engraved slab, hidden in the bedroom of Blade Master, the axedwarf...
15 Granite, 761: Two weeks into my plan to rule Deathgate once again, and I have the total confidence of the current Overseer. Deathgate is a solidly founded community now, and dwarves that settle here quickly fall into a routine, mostly of drinking and eating, and only occasionally plying any kind of craft. I aim to bring this fortress back to the days of its beginning, when every dwarf pulled together, and created this fortress from nothing. We may not be invincible, but, one day, we shall be.
I have advised that we begin producing cages once again, to line the entrance way. Let the goblins come. We will cage them, and each dwarf shall fight a stripped goblin prisoner, to teach them true combat skills. The gods know we need them. I also plan to extensively trap the surrounding surface, to keep our hunters and other surface workers safe.
The engravers complained that they lacked work, so I gave them a few short jobs in the Overseer's stead.
16 Granite, 761: Unbelievable. The Overseer was pulled away by one of the previous Overseer's clerks today. When he returned, he told me he had just discovered the true mission behind Deathgate. Apparently, the purpose of this accursed hole was always to breach hell and claim it for Dwarf-kind. We've even pierced hell itself, and through a devious use of traps and controlled cave-ins, a large demonic force was crushed.
No one knows. I don't know what is more infuriating. That I was not told when I was made Overseer nearly a decade ago, or that almost no one in Deathgate knows either. Or, perhaps even more maddening, is that this is almost certainly the reason I was struck with adamantine madness. It was the will of those demonic creatures that I release them from their prison. That they would think to use me as their tool is insulting.
I will complete the mission. Hell will belong to the dwarfs. The bastards brought it on themselves. I have begun plans to safely deposit soldiers and masons into the deep pits. Soon, work will begin.
