So since this is about 480AD we're talking about the object that had
just hurtled past Mars
NOT a big pile of rock
but a damaged ravaged
Space Cog
Space Cog?
You know
those roughly longboat shaped craft made out of space ore and eagles feathers that get towed about in the heavens by their crews of anthro Saturn Space Eagles
hauling everything from the rarest spices mined from Jupiter to blue skinned Venusian harem girls.
In this case the good ship Elsedore had been carrying a group of elven maids and families from Jupiter to a new colony on
Saturn when the Elsedore had been beset by flaming red hot
Barbarian Space Pirates from Mercury.
The colomist ship had been ransacked whilst her space eagle crew had been engaged in fighting elsewhere,then sent hurtling to her eventual doom when she collided with
Earth.
The dragon astronomers on Earth
being familiar with space languages
had detected the flashes of light coming from the still distant
Elsedore
it was a distress call.
And so whilst the space agles and the elven colonists tried to bring the huge space craft
under control
King Uther Pendrake stormed into the Castle garden,where Sir Braveheart
lay rolling about on the ground,yelping and having his fur
scratched by
Princess Aurora.
"Sir Brave Heearrttt" yelled the furious King
"Get up this moment,I have a mission for you
and Damsel Ciela.There is a out of control space cog
above us that needs rescuing,with one thousand
elven colonists aboard"
