All was going relatively well, the fortress of "Copperclaps" had bloodshed kept to a floor-moppable minimum, at least until the latest diplomat from the human civilization showed up........
Apparently he's a really nice guy, with this tiny small insignificant problem of happening to also be a fire demon. Well, in true diplomatic fashion, he meandered on through towards the fortress. The trees around him were rather quickly set ablaze, but the resident dwarves thought little of this, as SURELY they were snug and safe in their superiorly constructed rooms of stone. At least, they were until resident Baroness decided to attend the local party. The fire demon, being an obliging sort, thought he'd mingle a bit as well - get to know these people before setting forth his trade requests and alliances or whatnot....
Unfortunately, no one really took to his pleasant small talk, as shortly after he'd introduce himself he'd promptly burn off their face (and other fat) with his charismatic heat. Definitely not one to give up - he kept trying, but despite the perks of this no-diet slim-fest of his, all his social partners eventually collapsed into a rather morbid parody of Munch's "The Scream". Despite the obvious sparks that flew between them, even the baroness was hard pressed to keep a smile on her face, unable to concentrate on his chatterings all the while her dwarvenly heft was liquefied. Eventually even the massive booze she had imbibed at the party was unable to keep the pain at bay and she collapsed into an unconscious heap at his feet.
The fire demon diplomat, most unimpressed with this behaviour, left in a huff - reporting to the world at large as he fizzled his way out the front, and leaving a well charred party behind him, that he was VERY "unhappy"!
Hopefully with half the fortress dead (we are a very small little crew, and smaller now!) - this should convince the survivors of the perils of attending these parties, and they'll keep themselves at more dwarvenly pursuits of mining and smelting instead!
