You weren't a weak Tenno by any means, but you had never been a fighter like the others, and preferred to explore and discover. Albeit, it may have been a horrible idea, you couldn't help yourself; learning that Warframes could have children was fascinating, even if it seemed more like myth and legend.
Your friends tried to warn you--- told you to leave it alone because it couldn't possibly be true ---but you hadn't listened. Instead, you stole a few Warframe blueprints and fled to find the Warframe child.
It had taken you months to follow the breadcrumbs--- to discover the lore of Jade, Stalker, and their child ---but it meant nothing. Jade died giving birth to her child, and Stalker had seemingly disappeared off the face of the Galaxy, which left you scouring his lair for any clues to his whereabouts.
"Damn it." It was the umpteenth time of finding nothing, no matter how hard you looked. You didn't want to hurt him or his child--- only wanted to see the product of two Warframes ---but there was nothing.
Your ears pick up the sound of something moving in the lair, and though your eyes find nothing, you take it as your cue to leave. You don't get far before a scythe appears from seemingly nowhere, a scream spilling from your lips as it embeds itself into the ground, your body falling as you tried to get away.
"Why?" The voice, raspy and a mere whisper, makes you freeze up as you find yourself face to face with the Stalker. "Why are you here?" You knew the Stalker wasn't using this lair anymore, but the fact that he knew you were here meant he had to be watching you.
