Once, Talia was an assassin in the employ of Lubov Yemelin, a nobleman from Pendrago. She was the bastard daughter of Lubov, used as an assassin because he saw little use for her. She resigned herself to that life, while clinging to the twin brother trapped there with her. One of these jobs went wrong in the best possible way, though, and several of her friends fought to free her. She is not yet sure that she deserves to be free -- and she fears for her brother, who she wasn't able to bring with her -- but she has a shaky resolve to try to make something better of her life. Talia still uses ice magic and her short sword, Mirage, a strange blade with teleportation magic enchanted into it.
Talia has one magical weapon: Mirage, a short sword that has a single edge, and is slightly wavy like a eel. The sword is a former Divine Arm for a Seraph who died, and is imbued with some powerful shadow elemental magic. The great power that Mirage has is that, when thrown, it allows a wielder who has magically attuned to it to teleport to the sword. The sword has to hit something -- a person or object (including pieces of architecture or landscape) -- for that to work. The attunement is a simple process of focusing on it, until it mentally "clicks" into place.
Her fighting style was taught to her by Sasha Zhirov. It uses a short sword as the main means of attack, with a dagger as an instrument for off-handed strikes and parrying. It is very quick; Talia has customized hers to emphasize the short sword (because she can teleport with it), and favors her off hand weapon for defense.
Because she is from Lunar, Talia has the Blessing of Althena. She can use water and ice magic; she tends to favor ice, but does some thematics with mist. A lot of her spells are buffs and debuffs; Talia does, however, use black magic and has developed some offensive uses for her spells.
She also has a collection of items that she acquired. This was through entirely friendly means. These include:
Mirage: The aforementioned weapon can allow her to point-warp, which is useful in dungeons.
Golden Hourglass: Consumables from Spira, which can slow the flow of time in a localized area.
Royal Bomb: The bomb-fruit of Queen Anastasia, the Bomb Flower that lives at the Festina Lente with Talia and Amaranth.
