Taylor as a Guardian has been done before. But it's mostly been in the Worm universe, and doesn't really get to explore the Destiny elements. Over two years ago I posted in an ideas thread for a Destiny/Worm fic, and that's been percolating in my mind ever since.
The Taken Queen [on SB & FFN] is probably one of the best Destiny fics out there, but it's extremely niche. You have to know a lot of the background lore and do a lot of Grimoire diving to really grasp just how deep it is.
This is my take.
Paradoxical
"I remember everything about the day I was born. I still bear the scars.
"The Awoken are my family now."
October, 2631
If only he'd paid more attention the first time he saw her. Noticed her. But he hadn't, he'd been too focused on the sudden appearance of the Vandals on either side of the unprotected Awoken woman (their Queen, apparently) armed with spears that crackled with Arc lightning.
It wasn't until later, in the cockpit of the beaten Arcadia-class jumpship (he really needed to get something better now that he had enough glimmer) that his Ghost turned to him and asked, "Did you notice the woman standing on the side of the room?"
He frowned, glancing at the small, white floating star-shape. "What woman?"
"On the side of the room, when we were meeting the Queen," the Ghost responded. He —the Ghost had made it quite clear that he was male, with 'how easy it is to change voices, I mean really'— turned to look at his Guardian. "I would never have noticed her if I hadn't decided to go over the memory again for a better look at those Fallen. I think they were once a part of the House of Wolves. That was their colors they were wearing."
"Play it back for me?"
The Ghost's optic blinked on, a small blue hologram projecting onto the instrumentation of the jumpship. The view jumped around, largely focused on the Guardian's own in-video self, but there was a moment where it moved over to the wall of the room and then back, and he thought he saw something on one of the platforms at the edge.
"Did you see it?" the Ghost asked.
"Can you stop it at the right moment?"
"Can I—" his Ghost turned and gave him a flat look, the hologram winking away. "I don't think I need to dignify that with a response."
How the little things managed to be so expressive with only the effective equivalent of a single eyebrow he'd never know, but they made it work to scary degrees.
The Ghost turned away, and the blue-tinted hologram reappeared. It went through the same motions as before, except this time it paused on the wall, and now he could see the already-dark figure shrouded in shade.
Long, dark curly hair, and a lightweight armor of muted dark grays and black panels. She stood there uncaring, her back against wall, nothing covering her face other than loose fabric around her neck, but still so shadowed it was impossible to make out distinct features or even her skin color.
He would have sworn she was a Hunter, hand cannon strapped to her thigh and all, if not for the singular fact that no self-respecting Hunter would be caught dead without their cloak, or even just a hood.
The other two things that stood out were the symbols onto her chest and shoulder plates. The Queen's crown, in grey and darker grey rather than its normal purple and gold, was on the upper left of her chest plate, and a… beetle? of some sort, was on her shoulder.
"Strange. I wonder what she was there for…" the Ghost mused.
Did it matter? It looked like she belonged there, at the least.
Later, he really wished he'd given it more thought, but at the time, his focus was rather absorbed by the fact that he now had to go find a Gate Lord. Normal Vex Minotaurs were problems enough on their own, twelve feet of angry metal death-robots and all, but scaled up by three or four times?
He was not looking forward to this mission, even if it was necessary.
