From the Hero Preview thread on the HoN forums:
Beautiful and spirited, Aluna carries within her the essence of Earth itself -- the old Earth, long since lost to the decay of ages. Endowed with its might, and carrying the power of the moon in a mystical emerald, Aluna strikes at her daemonic foes with deadly speed. Thanks to her skill in battle, she has already become a celebrity among the heroes of Newerth.
Aluna is inspired by the life of a beautiful and spirited actress. Curious who our new Latina superstar is? Stay tuned to our HoN Facebook page for daily updates!
Skill previews:


Emerald Lightning - Aluna launches a bolt of lightning that bounces off her enemies, stealing their attack speed and leaving them stunned.


Power Throw - Channeling her strength into a single throw, Aluna is able to throw her weapon with deadly speed and accuracy.


Deja Vu - Aluna can see the past and future on the surface of moonlit water, and she can travel there under proper conditions.

Emerald Red - Aluna's emerald draws its power from the moon and increases the potency of her other abilities.
Her first two skills sound like they give her a nice mix of magic and physical damage nukes, along with some disable. The third skill description reads, "on the surface of moonlit water," implying that it works in the river and at night. The day-and-night system is an interesting mechanic that hasn't been explored since DotA's Night Stalker. A teleport-type ability would be very strong, though the "proper conditions" that are mentioned could limit its power. Her ultimate sounds like a passive ability, but considering the dual skill icons, it more likely can be activated to affect her other skills.
[S2] Idejder said that, while Aluna will be a Legion Intelligence hero, another row will not be added (Legion has a full three rows of Int heroes right now). Instead, an existing Int hero will "defect" to the Hellbourne side. He also stated that Aluna has carry potential, most likely stemming from the attack-speed-leeching of her first ability.
