He would try to bring a golden age of kobolds, inspiring crafts and metalworking the likes unseen to glowing yellow eyes before.
Many would regard him as a genius, a kobold truly ahead of his time and the single lynchpin into the revolution that took their race out of disparity and poverty, and into an age of self-revitalization and exploit.
In as few as a couple of days the cave will be turned into a kobold-styled dwarven hall that would, well dwarfs would still snub their nose at it but at least it isn't a cave anymore. Brewing will be discovered and the question of 'what do we do with a drunken kobold' would finally have an answer.
When his time is up the kobold will return back to his form as a dwarf, much to the surprise of those around him whom he's taught, and they would realize the boon that has been given to them and by who. Kobolds will be steadfast allies to the dwarfs for many years to come.
At least that's what he's trying to explain will happen to those around him in his gibberish screeching, drowned out by the cacophonous noises from the other kobolds present.
WWUDI allied with kobolds?
