Rome had been invited to a get-together of Germania and his people, with fresh boar for dinner and a warm fire to sit around. It was strange really, as Germania hated him no matter what he did, but Germania's answer when Rome had tried to ask why was clipped and almost angry, like always.
"Just shut up and eat. It's food, don't complain."
Rome being Rome, he had to not listen to Germania and keep talking.
"But why me, Germania? We are enemies."
"It is December twentieth, the start of Jul. We cease all fighting for twelve days and eleven nights to celebrate. And since we have been fighting, I have allowed you to feast with us as a temporary truce, my dear Roman. Here. Some ribs for you. Eat. And do not even think of complaining. If you wish for more, you may have it."
As Germania walked away to serve the wounded, Germanic and Roman alike, their meals, Rome watched him, stunned to silence. For as long as he could remember, he and Germania had fought, both with swords and with words. In fact, Rome remembered as he tried to move back to his own meal, a few of his ribs had recently been broken by a hard hit of Germania's sword.
A few hours later, as the temperature dropped and the sky darkened, Germania came over to where Rome was sitting with a blanket in hand. As he was wrapping it securely around him, he said thus:
"We are going to dance. Do you want to stay and watch or are you tired? You and I are sharing my tent. Don't worry, there is one Roman to every one of our tents. You and I are not the only ones."
Rome let out the breath he had been holding, wincing as the act hurt his ribs. It seemed to him that Germania was enjoying his plight, as his speech held a subtle happy lilt to it, even if his face didn't show his joy, no matter how sadistic it was.
"I will stay," despite the temporary truce, he would not show weakness in front of Germania.
"Fine. Are you warm?"
"I am."
"All right. If you need anything, just shout," he turned toward his people, "Nòtt über den Himmel geritten! Zeit zu tanzen!"
His declaration was met by cheers and battle cries, followed by music. Germania turned to face the fire and began to dance, followed by his own people and Romans alike. Amid the throng of people dancing and jumping around the fire, Rome watched as Germania looked up from watching his feet and raising his arms up to the sky.
Rome gasped in shock as he saw something he had never witnessed before, despite his and Germania's long history together.
A smile. Germania was smiling.
Translations:
Nòtt über den Himmel geritten! Zeit zu tanzen! = Night has ridden across the sky! Time to dance!
I used Google Translate for the translations, so I am sorry if they are not correct!
According to Wikipedia, Nòtt was a Germanic goddess, and her name means "night."
