"We're going to be alright, Glal," a voice echoed in my head. Mother's voice, the day the ship locked down and I lost everything while trying to find some medicine.

The void had poisoned my parents, turned them into monsters that my sister had to face alone. When the Zariman fell into chaos and I never made my way home. I would fall into one fight or another, the void pulsing under my skin, screaming to be let out. At night, I imagined little Si crying as the monsters approached. She was so little then. I couldn't imagine she had made it.

Now, I could hear her, not screaming, not crying, not dead, as I reminded myself. Her voice had deepened, and her words were carefully enunciated, a big difference from her squeaky, young speech. Of course, even with the changes, I should've recognized her during the Old War. We worked together, her skill at infiltration and mine at elimination made us a matched set.

Now, I'm itching to finish my vault and get back to her. She was probably still working on her vault, and if I could finish quickly I could help her.

I turned the corner, glancing through the vent at the data vault and its guards on the other side. I'd been rushing through the ductwork, and a part of my brain that wasn't worried about the slave device in my sister's frame's leg had made a witty commentary on how large the ducts simply were, mocking their designers. It was like these people wanted break-ins with warframe-sized air conditioning systems.

I kicked the vent out, nailing one guard in the head with a piece of metal. I stepped out, swinging my shildeg into the chest of the man. An alarm went off somewhere in the complex, distant, but enough to send a shiver down my spine. I stomped, and Virulence spread, advancing in an arc of deadly infestation. The sooner I finished here, the better.

I stalked over to the wall of the vault, climbing to the top. As I went, I tapped the comms.

"Who set off the alarms?" I asked. A choked Grineer scream echoed over the channel.

"Must be Umbra," Titanium whispered. My eyebrows scrunched.

"Why are you whispering?" I whispered.

"Because there's a soldier right in front of me."

I blinked.

"Hit him!" I yelled. She roared and after a handful of clangs, clatters, and screams, her voice came back over the comm.

"Thanks, Gee!" She said. I blinked.

"What did you say?" I asked.

"Hold on, I'm in the vault," was all that came back.

"But what did you call me?" I asked again.

No reply. I jumped off the walkway down in the vault, rolling my neck and ramming my paragon into the port. I used a cipher and was done in a millisecond, and crouched to jump out, a bit agitated from the old nickname. For so long, that's what we were. Siyanda and Glal. Gee and Si.

I jumped, eager to track her down for an answer. Maybe she was remembering more?

Whack! I crashed against the ceiling. What just happened? I fell, looking up at the hard surface lined in harsh green lasers.

I growled up at the hard surface, pulling my Basmu from its spot on my back. If they thought they could keep me of all people trapped in here, then they were wrong. I'm a Tenno. My people were not caught easily, not kept.

I fired, the bullet whizzing through the air and striking the wall. I was getting out of here.

I reopened the comms channel.

"Titanium, Umbra, if you haven't gone into your data vault yet, do not enter. I repeat, do not enter!"

Static echoed over the channel.

"Umbra, Titanium, can you hear me?"

"They can't hear you, Tenno, nor will you escape."

I swiveled and fired at the bloated face of Vor.

"Your partners, you, are difficult beasts to contain. Our factions of Corpus and Grinder don't agree on anything, and I would rather kill one than speak to him. But, their technologies are to be commended. Their laser system works fine, as do their scramblers. Like the Orokin of the past, the raging monsters of the Void have been contained. And soon, another of the beasts will be mine."

"I will return for you, if the other insists on death."

I snarled and jumped, hard, at the wall that he stood on the other side of. He smiled as I banged against it, and uncharacteristically turned, and walked away. Keep him talking, that's what Si would say. Knowledge is a valuable commodity.

"Come back here, you maggot! Face me!" I snarled. I thought of what he might have cut his monologue short for.

"No," the worm in question sneered over his shoulder. Then he turned a corner and was gone.

"Titanium, can you hear me?" I said, testing the scrambler again. The vault simply echoed my words back at me mockingly. I jumped again, landing on the platform below the entrance. I punched. I swung my Shildeg. I fired repeatedly.

"Vor! I will not be contained!" I hopped down. What would Umbra say? Or Ordis?

My mother's voice sounded in my mind. The last day of my mother's sanity.

"Watch her for me. Don't let go."

I jumped down from the platform. What would Siyanda do? Right now, she was going off of her instinct. But during the Old War, she was one of the best infiltrators and spies. She walked slowly, softly, undetected. She waited until her moment to unleash destruction if need be. She could hack anything in picoseconds.

I breathed deeply, feeling the Void rumbling under my skin.

I approached the console and began plugging the tabs into their spots. After a couple of seconds, there was an affirmative bing. I smiled a wolf's smile.

It would be a warm day in the Void before a Tenno admitted defeat or bowed to a new master.
