It's June 9th, the day known as Shield's birthday. And the commissioner celebrates his birthday in the way he always celebrates: With video games and endless streams of mead and beer. But all birthdays are vulnerable to being crashed, even one in a town known for its peace.

The trouble will come in the form of an orc warband led by Cap'n Killteef, an ogre warlord of dubious reputation. He and his band of merry murderers plan on wiping out Ponyville in an attempt to add glory to his name. His motives are meaningless to Shield and company, they've got mead in their bellies and their rage in their blood. They will be more than happy to fight off the horde.

But the fight will not be just against Shield and buddies, since Killteef wants to turn Ponyville into his new base of operations. And he will do so through the use of one of the Ogre's most complex tactics: throwing his inferior orc cousins at the enemy until they stops moving.

Will the commissioners be able to hold back the green tide? Or will the horde inevitably overwhelm Ponyville through sheer numbers?
