"Wake up... Come one, wake Up Tiy!"
Floating above a metal ring with a single blue light on it's front blinking, a ball of light glowing in many spectra rushed about, activating devices and hurriedly trying to wake it's friend. "Please, get up! What ever is outside the entrance, have discovered plasma torches at least." As it finished, the rings split into three rings, each one set inside the other, and slowly began to spin almost like a gyroscope. "Yes!" Was all the orb got out, before the torches ceased, and heavy metallic banging resounded throughout the cave, as the Ethereals tried to bash down the remainder of the door. "No!"
The rings spun faster and began to glow white, and as the rings turned to a blur, there was a flash, and all was still, save for the repeated thudding. Where the rings stood, was instead a hooded figure, wearing long robes of dark green and silver, and gold trim along the cuffs and bead of the hood. The figure stood up, and yawned, stretching her arms above her head and scratching her back. "Hello Sage," she said sleepily. "What seems to be the pro-"
"NO TIME, THE DOOR, NOW!! BLOW IT UP!!" Quickly snapping to attention and realizing this was serious, Tiy flung a large glowing beam of incandescent yellow energy at the entrance and ducked behind cover, as the doors caved in. The Matron standing on the other side stood dumbstruck as the screaming, raging stream of death flew right at it, and could only manage to bring it's blades down in front of it as a desperate last chance of self preservation, before being blown to pieces by the explosion. Sisters scattered for a second from the shockwave, before flying in through the entrance, and taking point against the Warden, raining down quantum energy fire at her position.
"What the hell!? That's Yss'Tkul, isn't it? I guess we lost the war, then..." The Warden materialized a sequence of razor sharp shards above her head with a flick of the wrist, which shot out at impossible speed and impaled each of the five's Sisters Cores, shutting them down. "Why are THEY here? And why are they DEAD!?"
The Sage floated down beside her as the two other Matrons entered the room, firing heavier cannons and forcing Tiy to move to another piece of cover in a diving roll. "I'm sure you have a lot of questions, Madam, so let's start with current events... There are two cruiser class vessels, probably Yss, fast approaching the installation and probably charging weapons by now. The Yss know for a fact that the Heart cannot be destroyed so easily, so they'd rather dig it out than drag this fire fight out any longer. By the way, you still have it, right?"
Tiy reached into the inside of her robe, and pulled out a small perfectly smooth sphere, dull grey and with no external markings of anykind. "Of course I still have it. That's the whole reason I'm here, Sage. How long do we have until they arrive?" Tiy launched another energy wave in their assailant's direction, blowing off some armor and critically damaging a Matron's leg with a loud metallic smashing.
"About three minutes... I'm going to assume you would want to phase to anywhere else that's not here about now?"
"Yes, though keep it to within the star cluster. I'm still a little tired from all those millennia sleeping. And make sure it's somewhat safe, I'm gonna need a few days to rest after this one."
"Understood." The Sage grew to twice it's size, glowing yellow, and seemed locked in thought, swirling and searching for a destination fitting those constraints. Tiy continued to fight the Ethereals, finishing off the other uninjured Matron as more Sisters flew in. Above ground, the cruisers began to descend, ready to obliterate the facility. "Ah, here's a pretty one... Nice beaches, excellent food, friendly locals-"
"That'll do!" The Warden plunged her hand into the Sage's swirling glowing mass, and both of them disappeared in a flash, leaving the remaining Ethereals to ponder whom they had just fought. And what would happen when they returned empty handed.
