Times are a-changing in the lands of the Diamond Dogs, and not for the better. Beset by the dangers of the surface world, their newly-established above-ground kingdom of Diamondia is in need of aid from friendly neighbors. Luckily, they just happen to be within a little over a week's journey of the most friendship-loving beings in the world! Surely the most loyal of canines and the friendliest of equines can work something out with only a minimum of misunderstanding, culture shock and inadvertent acts of war, right?
