PROJECT: Line
The skins are for Leona, Fiora, Zed, Yasuo, and Lucian! He doesn't seem to fit, but that one talking about blazing and fire. The light could be pointing to Jax's lantern tho. The trace lost is obv a dead end. :D
"Brilliance in pieces, shrouded in ethereal flame. Protector, light bringer. Lone voice. Stand and Fight. In death heavy fields, now still she stands, light washes over..."
Leona's quotes in game is even "Stand and Fight."
"Piercing flame, he, cast in light. I see his vision, free from shadow, a blazing melody. Beyond the light, nothing, purity bound in fury..."
~~This is the confusing one. Thinking again it could be Jax, Shen, Renekton, Brand, maybe someone else. I said why for Brand and Jax already. Shen "free from shadow" could mean free from Zed after killing his father, Renekton simply for the "purity bound in FURY" and "free from shadow" after being locked away with Xerath forever. ~~
"Dark sight, shadows marked, death lives beside. Silencer, he follows. The shadow is within. Blood soaked, he stands. Vanish..."
Shadows marked. Death mark. Zed.
"Weaves, unweaves; unraveled defense, dashing forward blade gleaming. Caught orbiting one vision, dashing, striking, blade dancing..."
Fiora's old ult was Blade Waltz. And her style is obviously dancing.
CONFIRMED. It's Lucian! :D Piercing Flame (Ardent BLAZE, and Piercing Light) Wasn't thinking ranged. Good work guys! :D
Thoughts on the Image of that dude with the ponytail. It COULD be Jax (those 6 lights on his eyes point to him with his weird face thing, but it's also VERY similar to Yi). AND. I think it could be Xin Zhao? He also has that ponytail look. So those are my thoughts on the trace lost.
is. Also, Fiora while matches with the description almost to the dot, does not have an "unraveled" defense. To unravel means to let go, or unleash your defense. 
's equilibrium strike unravels her lower health as her greatest defense because her opponent often will take extraordinary damage from her hiten style while they're stunned.
) to have a skin. Plus 
also JUST had a skin recently (2 months ago), so doubt that, especially when it was already a 1350... he doesn't need two of them in a row since the PROJECT skins have to at least be 1350 due to the effects.
