The Lying Herder-Boy
There was once a young servant-boy who longed to be noticed, yet his tasks were dull and unlikely to bring him the attention he desired. Scrubbing, cleaning, tending the herds; these were not tasks in which legends are born.
One day, as he was tending his House's rothé herds, he decided to try to get attention for himself.
"The svirfneblin," he cried. "They are raiding our rothé herd!"
He raised so great a fuss that warriors came running. When they arrived, he told them that he had driven off the cowardly deep gnomes and saved the herd.
They did not challenge his words, but one of them scoffed at the notion that mere deep gnomes could get so close.
The boy watched them leave, and felt bitter, knowing he still did not have the attention he wanted.
Since even the most foolish drow know one should not try the same lie twice, he sat down and thought of a new foe to blame.
The very next cycle, therefore, he cried out, "Hook horrors! Hook horrors attack the herd!"
Warriors came running, and he told them that his shouts had frightened the monsters away.
The warriors glanced among themselves, and then kicked and struck at him, giving him many sharp blows.
One of them growled to him, "Fool! To lie is one thing, but you lie without knowledge and so insult us. A hook horror hunts using sound, and would have killed and eaten you."
For being found out in his lie, and for thinking it through so poorly, the warriors took him out on their patrol and staked him out as live bait for hook horrors. A hook horror came and tore him apart, and began to eat him, when the warriors used that diversion to kill it in a surprise strike.
They rode home on their lizards and were praised for doing their duty so well, and a new guardian was chosen for the rothé herds. The old one was forgotten forever and his name never spoken again, as he deserved for being such a fool.
A/N: This 'boy who cried wolf' variant comes from the fact drow would get a whole different set of moral lessons out of the story; if you're going to lie, do it well. Also, as if drow would believe something like that more than once... or let it go unpunished.
