Went a little Warhammer 40k on this one.
Prompt: An asteroid heads for Remnant.
In the vast darkness of space, a large asteroid flew between the stars at an incredible pace. But it didn't fly without purpose.
Scattered along its surface, a large band of Orks were gathered around their numerous camps.
Long ago, their Warboss had a brilliant idea: Strap a bunch of rockets to an asteroid and use it as a ship to invade a world and crush the 'ummies and collect their skulls on their pointy stickz!
It was fool proof!
Unfortunately they missed the planet and went off into deep space. But years later, they came across another planet, and their moral sored as they final will be able to do a great war.
Unbeknownst to them, it was ancient Remnant.
"listen up ya rotten gits," the warboss shouted to his arranged. "'dat 'der world iz gunna be ours soon! we're gunna konqua it an' take all uv 'da loot an' dacka we kan! an' den we're gonna go ta 'da next world, an' so 'da galaxy why us orks are 'da biggest an' 'da strongest!"
"WAAAGH!" the orks chanted.
"get ready Boyz, ere it komes!" The orks cheered as the planet drew closer. The cheers died down when the planet was to their side. The cheers were dead when the planet was behind them.
"Wot? We missed!"
"um boss, were hed'n for 'da smalla white planet!"
"Wo-"
The asteroid then crashed into Remnant's moon.
The orcs all went flying into space as the rock was destroyed and half Remnant's moon shattered.
Those rascals. What will those green skins do next?
