The Slaughtering Slaughteryness of Slaughtertude
Queen Urist wanted the creature dead. But she still wanted to fight fair. So she sent two marksdwarves in. She thought sending the squadleader Lord Lego in would be overkill. How could it possibly take three dwarves to kill that thing? It's only size 30,000!
Anyways, Cheddarius and Xanthius were there, and here is there fate, recorded for all to see...

Lord Lego had survived death once. Here is his second less successful attempt.

Huesoo the newly arrived Hammerer is there to stop the now wounded and crippled beast. He swings and misses, the beast runs upstairs to get away from the dwarves. Huesoo follows...and behind him rushes Akhier and Lord Dullard's entire squad of men...

The Beast of Microcline killed 6 dwarves outright, plus 3 through terror and starvation, and also, he killed a horse. He singlehandedly killed about one fifth of our fortress population. I'd say that was a pretty successful terror spree.
