The Praetor and the Spartan

Authors Note.

I was scrolling over some crossovers and found out that this kind of thing hasn't been done. If you feel strongly about my choice of subject please comment. So let's get to the obvious part, shall we? I do not own The Heroes Of Olympus or Halo, Rick Riordan and Bungie do.

Chapter 1: The Dream

Reyna woke up shivering, Venus' words from all those years ago still reverberating inside her head.

"No demigod shall heal your heart."

She got out of her bed reminding herself that it was just a pointed barb from The Goddess of Love.

She went over to the mirror, to look at her once lush black hair. She figured that probably all the stress she took upon her shoulders as the solitary praetor, whenever the need arose, had taken their toll on her appearance. At 36, she looked at least 10 years older with worry lines and grey hair becoming a common feature in her proud face

But it wasn't those words which made her frightened, it was the vision that she saw

….

She was standing in the central plaza of New Rome. The avenue was lined with the bodies of Greek and Roman demigods.

Before she could assess the damage properly, she was shocked by the presence of an army of humanoids who seemed to be the reason for this destruction.

They were armed with energy swords and laser rifles. She felt as if she were sucked into a sci-fi flick from the old days.

Scanning the mass of the defenders, she saw her fellow Praetor Frank Zhang leading them in a line formation.

"Zaap" went one of the alien's weapons and down went Frank with a groan

"Nooo" she screamed and found herself sweating like hell in the dark

….

"I must contact the others. It's been a long time since I've had such a dream". She told herself grimly.

As the damaged spaceship hurtled through space, Cortana was talking to herself" I'll set the trajectory for the nearest inhabitable planet for now."

Cortana sighed as she watched the Master Chief in his cryo-tube. She was interrupted during her musings on the Master Chief's color scheme, by an alarm.

"What the…." I guess John will want to know this."

She set about decompressing the Spartan-II super soldier.
