WHAT'S NEW:
** Introducing a previous encountered Boss enemy: Shahdee, she is most likely a minor antagonist in the game.
_ Some say that Shahdee was created in the Empress' own image. Like everything else on the island, she exists to serve the Empress of Time. But, unlike the rest of the Sand Creatures, she enjoys a small degree of autonomy, functioning as the Empress' second in command. Nevertheless, the Empress is not the kindest of masters, and Shahdee has suffered years of terrible abuse at her hands. Over time, she has come to hate her maker, secretly devising ways to either escape the island or kill the Empress. She's just waiting for the right opportunity to present itself.
_ As a trusted subordinate of the Empress of Time, Shahdee is charged with the duty of ensuring that the Prince does not reach the Island of Time. Shadhee departs with the knowledge that the Empress will kill her if she fails in this mission, but Shahdee believes that her mission is pointless; she is convinced that fate cannot be changed or defied, and that one way or another, the Prince will get to the island, and he will end Kaileena's life, even if she attempts to stop him. Despite this, Shahdee's loyalty to the Empress of Time is such that even though she believes it to be a fool's errand, she will do everything in her power to try and make sure the Prince does not reach his destination.
_ Shahdee and her crew of sand Raiders attack the Prince's ship during a terrible storm at sea. While visibility is low, the massive attacking shipboards and sets fire to the Prince's sinking vessel. Mercilessly, the sand demons slaughtered the Prince's crew and Shahdee beats the Prince in battle, launching him into the ocean with a powerful kick.
_ Naturally, Shahdee fails in her mission to keep the Prince away from the Island and falls into conflict with the Empress of Time. Shahdee chafes under the Empress's rule, and finds her mistress's determination to defy the timeline to be illogical. However, Shahdee meets her end at the hands of the Prince, angry for the needless slaughter of his crew. He stabs Shahdee through her torso with the Spider Sword in the center of the Sacrificial Altar. The girl in black bleeds to death and takes her final breaths, while she's citing that they cannot change their fate.
_ At first, the Prince assumes that her message is for him, and that she was referring to his attempt to change his past and stop the Dahaka from pursuing him, but it is later revealed that the message was actually intended for Kaileena.
_ Shahdee's death remains a form of torment for the Empress, as all is coming to pass exactly as it was foreseen.
_ Shahdee has a quite provoking sentences that she repeats them during her fights with the prince as following:
{Tell me when you're going to fight for real} {HOW! How can this happen, I won't give you the satisfaction of seeing me fall} {You don't honestly believe you can defeat me} {I will not fail the empress} {This is just the beginning} {You have two choices, run or die} {You have no place on this island} {Flee, while it's still an option, fool} {The empress will be pleased with my success} {Is this the best you have to offer?} {You call yourself a master swordsmen?} {Fool, it's as i told you, you cannot change your fate, the empress worried for nothing} {He was fool to challenge my mistress} {Submit prince, you only succeeding in wasting your time} {Rise! Rise so that i can strike you down once more} {Leave this island prince, while escape is still an option}
