It was June 21st, and our story starts in the throne room of the Olympians. As usual, not much was being accomplished. Zeus and Poseidon were arguing over everything, ranging from who was the favorite son, who was more powerful, and who wore a toga better. Aphrodite was staring love struck at a mirror, Hephaestus and Ares were fighting, and Apollo was spouting off the worst poetry to ever be heard.
It would have continued all night, had a sudden burst of light near the door not occurred. Most of the Olympians jumped up, readying themselves for a fight (Aphrodite of course couldn't be bothered with something like fighting!) When the light began to disperse, the Olympians were shown who their intruder was. Eru, the creator of another pantheon, stood by their throne room doors.
All of the Olympians but Zeus and Ares retreated to their thrones, content to hear what Eru had to say for himself. Zeus because he was the king and wasn't about to give in so easily, and Ares because he was Ares.
"Who do you think you are, to waltz into my kingdom as if you are its lord?!" Zeus roared confrontationally, lifting his lightning bolt up as if preparing to strike.
"Peace brother, hear what Eru has to say." Poseidon said, before mentally adding, "We have only just finished the Second Titan War. Will you be so quick to start another by striking someone of such importance?"
Zeus conceded reluctantly, before once again taking his seat, and motioning Eru to step forward."What have you come for, Eru? It's been a long time since we've last had business between us, and so far as I'm aware, we've done nothing to warrant such an unexpected visit."
"Forgive me," Eru rumbled, his voice sounding like everything and nothing, creation and destruction, "but I wish to request your help in a matter concerning both of our worlds."
"Don't you think I know enough of my own realm to know when it's in danger?" Zeus questioned, angry at the perceived insult.
"That is not what I meant to say, I know you watch your realm carefully. However, the threat I'm speaking of comes from my world. You remember Sauron, don't you?"
"I do, but he fell long ago. What does he have to do with anything, and why would it concern us? He wasn't a threat last time, and how can someone dead possibly hurt us now?" Zeus asked, amused at the other king's unnecessary worry.
"He's a threat because the one ring was never destroyed. Sauron will live as long as the ring exists. For the past few millenia, he has lived as a shadow of himself in whatever dark place he could find. But the ring has been found once again, and Sauron has already sent out his servants to reclaim it. This concerns you because the barrier between our worlds is not as strong as it once was, and if he wins the war, he will continue on to Earth. Before he was last defeated, I had heard that he was disturbingly interested in your realm, that he wished to fight with you." Eru warned. "Your world is far more advanced than mine, but your people would not stand against the forces of Mordor. Imagine the chaos of Orcs, Uruk-Hai, Trolls and whatever other beasts Sauron has control of running rampant through your streets. The majority of your people have long forgotten what lingers in the darkness, and have not the knowledge to fight. It would be best to eliminate the threat before it is a threat."
"What do you mean "Eliminate the threat before it is a threat?" Do you expect the Olympians to go fight your war for you?" Zeus said mockingly. "Why shouldn't we just strengthen our walls, hmm? We just finished our own war, we have no wish to enter another."
"I have no wish for a member of another pantheon to enter my world." Eru said cooly, the beginning of anger stirring in his eyes. "What I have come to ask for is the help of one of your demigods. One of my Maiar have foreseen one of your children fighting in our war. I have looked too, and she seems an excellent warrior."
"Just who have you seen, not my daughter Thalia?" Zeus said quickly.
"No. The girl I've seen has black hair and green eyes. I believe she's Poseidon's girl."
"No!" Poseidon roared, standing from his previously relaxed slouch. "My daughter has seen far too much for one her age, I'll not have her going and fighting another war!"
"Relax, Poseidon." Eru said. "I would not just throw your only daughter into war. I have seen that she lives through the war, and finds happiness. You know that she is not content with the life she lives now. She's too much like the sea for something so routine and safe as going to school, graduating and getting some boring job. Besides, she would be safe. I can promise you that."
"No, I will not let you-"
"Yes! Absolutely! You can take her when you leave if you wish to!" Zeus said, suddenly all to happy to make a deal with Eru.
"Zeus!" Hear scolded, "you cannot just promise to give away someone elses child, illegitimate or not."
Poseidon smiled, relieved, "Thank you, Hera, you're not as bad as I thought you were."
"No," Hera spoke over Poseidon, "this is something the council has to vote over. All in favor of sending the disrespectful little smart mouth away, say aye."
"What?! No! I take it back, you're worse than-"
A chorus of ayes were heard, with only five disagreements being heard. Thunder boomed to signify that the deal couldn't be overturned.
"It's decided, Poseidon's daughter will leave with Eru today!" Zeus said happily, before Eru raised his hand to signal for quiet.
"No, give the girl a week to say her goodbyes and pack, she will leave at noon on the last day. I suggest giving her something to hold everything she wishes to keep, for they will be traveling far, and perhaps a method for communication, for she won't be able to come back to Earth again."
Silence rang through the room, before Poseidon spoke up again. "What do you mean when you say my daughter won't be able to come back again? I thought this was just until the war was ended."
"No," Eru spoke. "I had thought it was obvious from how I spoke earlier that she wouldn't be able to return once her quest was finished. Once she leaves Earth, she won't be able to return again. The travel between worlds for mortals is one way only."
While Zeus, Ares, and Hera smiled at hearing that, many of the others were upset or at the very least displeased with the turn of events.
Seeing that the decisions concerning the long term quest were set, Eru turned to Poseidon, handing him four mirrors, saying, "These are for you, her mother, her brother, and her. They will allow you to communicate. I'm sorry for what must be done, but it is far better than what would happen should nothing be done."
Having done what he came to do, Eru turned and disappeared just how he came.
Poseidon put his head in his hands for a few moments, before standing and heading for the door.
"Where do you think you're going, brother?" Zeus questioned, still happy with what had happened.
"I'm going to go tell my daughter and her family what you've decided for her. Hopefully she can forgive me for what we've done."
With that, Poseidon disappeared to tell Andromeda Jackson that she would have to go on another quest, and that there wouldn't be any return from this one.
