Tali is a character from an abandoned web serial I was writing, ConstantChaotic (CC).

The artist is "princessmizuki27" but they don't seem to have an online presence anymore (this art is at least 7 years old).

About CC:

In the world of Gaia, people have Resonance Souls. These souls grant them special powers. But some of these powers are feared. The ones of most relevance are The Prophecies, which consist of The Phoenix and The Soul Stealer.
These Resonants are so strong that factions exist to try to stop them from destroying the world.

In a world that believes in prophecy, do you think you can change it?
The League has sent a Monte Criston to destroy The Phoenix, whose current reincarnation is in the country of Dexterity.

TALI HEARTLIE

This girl is adept at controlling, creating, and manipulating fire. Her hair is a fiery color and gives the appearance of fire itself. Tali's heritage reigns from a line of mafia kings, and her Rez is seen as a testament to this.

Tali herself is a rather crude person. At only fifteen years old, she already says whatever is on her mind at the time, and is rather spoiled. Her parents gave her whatever she wanted, boyfriend included.

After being killed in chapter nine, Tali resigns herself to make her life “worth something” by stealing everything she “needs” to make a happy home with Fortenra.
After the boy left her, she becomes confused in her self identity, and longs to have him back- even if that means killing others or destroying anything that comes into her path.
The more often Tali dies however, the more detached from reality she becomes.
