If any of you are familiar with Greg Panovich's work, you might have seen his sith panthress, Delin Gri, and notice that this batress has a similar name. In a way that was purposely done. Dela-Gre rivals Delin Gri and have talked about co-oping their story sometime.

Dela-Gre is a sith assassin. She is trained to eliminate the enemies of the sith with deadly accuracy and at all costs. She has four dual lightsabers and hidden on her back is a holster for her secret weapon, a black lightsaber, that has the properties to drain energy from energy fields or machines that it comes in contact with.

She was given the name of Darth Ferno upon completing her given assassination test by her master, Doral Menson AKA Darth Vasion, to eliminate a feral tribe of bats that have terrorized Dela-Gre's people for centuries, a tribe in which a lot of anger and resentment was focused towards. The object of her hate destroyed, she was free to unleash her rage onto the enemies of the sith.
