Then suddenly horrible, horrible monsters were rushing up the tunnels, killing everything in their path!
I told everyone to hide in the main hall, but it was too late. The... THINGS from beneath killed EVERYONE.
My soldiers, my peace-loving craftsdwarves, my new parent-dwarves... None were save. Only ONE DWARF survived, as I ordered him to hide in one of the new, wooden houses I'd built apart from the main hall, a small but comortable affair, with two apartments with seperate entries. He hid in there, cowering in terror, (He had been elected mayor, incidentally, as everyone else was dying horribly) as the demons razed the ground outside.
He could still hear the terrified squeals of animals as the demons TORE THEM APART, and ATE THEM ALIVE!
Then, something REALLY CrAZY happened.
'Some migrants have arrived!' "Nooo!" I screamed. "Save yourselves, you fools! Turn back, before it's too laaate!"
Of course, they didn't hear me. And with grand ideas of their new lives at the Outpost Treatyquested in their heads, they continued onwards, leading their pack-animals and young children. By the time they saw the flames on the horizon, and heard the chilling screams... It was too late.
The foul demons flew at them, mouths wide in their ETERNAL HUNGER for LIVING FLESH... Some of the newcomer's nerves broke then, and they turned and fled, only to be cut down on the fields surrounding the fortress. Some brave fools, however, pushed on for the fortress, dodging the demons and running madly... Only about six-seven survived, making it to safety in the apartment next to where the mayor was hiding.
A couple of them were still ON FIRE as they ran in, and promptly dropped dead.
From there on, DF became like some kind of survival horror!
The surviving dwarves were in shock... They'd seen their families and friends torn apart before them.
After a while, the demons outside seemed to settle down once everything was dead, and they sort of stayed in the upstairs part of the fort's main building... I sent the mayor out, un-forbidding the door to his apartment, and he crept across the wastes to the food stockpile, and promptly got drunk. *sigh*
Then, he spotted movement... There was one bizarre-looking demon tormenting a pet bunny. Whether the mayor was some kindof heroic badass or just drunk I've no idea, but he ran towards it, much to my dismay.
Despite me repeatedly ordering him to turn around, he ran towards the demon and IMPENDING DOOM, and promptly... Killed it in two punches.
Anyway, after that it was pretty fun, I kept sending my dwarves out to gather food and weapons and such, (exept for the mayor-He was running around in the nude) and it was all going peachy until some demons spotted them... They fought to the last, a real credit to the mountainhomes, and managed to kill a few before they died.
