Trace 1 - "Trace Lost"
I believe this is a new champion.
Trace 2 - "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..."
I believe this is Karma. Ethereal Flames are literally her entire theme. And in her lore she protected her village as it's lone voice when nobody would raise a hand in violence even to defend themselves. 
As the Noxians advanced, the villagers prepared to accept death, bound to their peaceful vows. But Karma would not accept death and instead saw another way: sacrificing a single life to spare many others. To save her people, she drew upon the power within and summoned the full force of her will. A burst of spirit fire emerged from her body and spiraled towards the Noxian general. The flame took the form of twin dragons, the symbol of Ionia itself. It was the first time Karma had ever used her powers to harm instead of protect, and neither she nor the villagers had ever seen anything like it. When the magic subsided, the general had fallen before her and his soldiers had scattered. The opposing forces surrendered to Karma's strength leaving her people, and their traditions, untouched.
Trace 3 - "Piercing flame, he, cast in light. I see his vision, free from shadow, a blazing melody. Beyond the light, nothing, purity bound in fury..."
Everyone thinks Piercing flames and shadows involve Lucian HOWEVER, I'm almost positive this is LEE SIN. 
In Lee Sin's lore, as atonement for committing the one taboo of alchemy, human transmutation(not really, but basically the same end result, disfigured human and the creature died) he set HIMSELF ON FIRE. Lee Sin, he, cast in light, became reborn, free from "shadow" or his arrogance while he was young. That which caused the agonizing death of a young boy, and an entire village.
A symbol of purity, and the "Dragon's Rage", he was the Pure, bound with Fury
**Trace 4 **- "Tempest, a blossom caught in drift, fluid form. He speaks. Death is like the wind... he is a storm, blade howling... Always by my side..."
Yasuo, this was a given. 
**Trace 5 **- "Dark sight, shadows marked, death lives beside. Silencer, he follows. The shadow is within. Blood soaked, he stands. Vanish..."
This is probably Zed, no doubt. 
Trace 6 -"Weaves, unweaves; unraveled defense, dashing forward blade gleaming. Caught orbiting one vision, dashing, striking, blade dancing..."

I believe, this is Master Yi OR Irelia. Weaves/Unweaves might refer to Alpha Strike or Bladesurge.
Might be more related to Irelia. Unravel means to undo, or release. Her equilibruim strike is used when her health is lower than her enemy's, so she unleashes her strongest defense against her enemy, a stun.
Dashing forward gleaming blade, Irelia's hiten style causes her blade to gleam, but the same goes for Master Yi's Wuju style.
Orbiting Vision - Irelia's blades "Orbit" while dancing. Master Yi has an absurd number of eyes(that or his goggles are for show) and could have "orbiting" vision.
But I believe Ionians best suit the "Project series" since Yasuo and Zed are the starting 2, and just so happen to be from Ionia.
