14th Galena - Inod Dodókrobek got the thing's attention and drew it up towards the upper gate where there still remain some traps unsprung. He tripped while running and his wife, with their child strapped to her chest in a truly dwarvern fashion, charged the thing, crossbow loaded. They paid for their bravery with their life.
Her child, which she managed to fling away before this thing crashed down on her body like a mountain, landed nearby in the mud, still alive. Crying for his mother.
Still the thing charged.
I ordered my dwarves into tight squads, based around their fortress duties. The woodworkers, I armed with ropes and chains, and set them up towards the entrance with standing orders to wrestle the thing to the ground, in the hopes that we could possibly subdue it and cage it.
It finally reached us. Kadol Giginlitast charged out to get the monster's attention in the hopes of giving the rest of his squad a chance to circle around. He was swatted away like a buzzing insect, dying immediately from the immense strength of the creature, but he gave his squad the opportunity to start throwing ropes around colossus.
When all was said and done, the brave dwarves of the Silvery Eagles pulled the thing down to the solid earth and bound it with wrought chains.
And now, it sits in a cage, awaiting my decision as to what to do with it.
