Prince of Persia Warrior Within Story
Box art Cover

Seven years after the Prince used the Sands of Time to turn back time
and rewrite history, he finds himself hunted by the Dahaka, the Guardian
of the Timeline. Because the Prince escaped his fate, the Dahaka is sent
to ensure that the Prince dies and thus restore order to the Timeline.
Seeking council from an old wise man, the Prince learns of the existence
of the Island of Time - birthplace of the Sands of Time, governed by the
Empress of Time. Thinking only of himself and his survival, the Prince
sets sail for the Island to prevent the Sands of Time from ever being
created. His belief is that if the Sands are not created then there
cannot be a Dahaka.
Many obstacles attempt to prevent the Prince from reaching the Island
and his goal. First, his ship is attacked by an army led by a mysterious
woman in black named Shahdee. The Prince faces her and during the
ensuing combat she manages to throw him overboard; his ship sinks and
his entire crew perishes; however, the Prince manages to survive and
drifts ashore on the Island.
Wandering further into the island, he re-encounters Shahdee, whom he
pursues deep into the fortress of the Island. By doing so, he
accidentally steps into one of the many Portals of the fortress, which
connects the present with the past. Continuing his pursuit into the
Past, he finds her trying to murder an unknown woman in red named
Kaileena. The Prince engages Shahdee once more in battle, kills her, and
saves Kaileena.
Denied an audience with the Empress of Time to state his case, the
Prince is then faced with the task of activating two towers, which in
time will open the doors to the Empress' Throne Room. Kaileena aids the
Prince by presenting to him the Serpent Sword, which will activate the
bridges to reach both towers, and eventually the Lion Sword, an even
more powerful weapon than the Serpent Sword. As the Prince explores the
island, he occasionally encounters a mysterious, dark-looking creature.
Shortly before reaching the throne room, the Prince is attacked by the
Dahaka and almost killed, but the dark creature rushes in and sacrifices
itself to save him. The Prince eventually succeeds in reaching the
Throne Room only to discover that Kaileena is the Empress of Time. She
had sent Shahdee to kill the Prince, sent him on the perilous journey to
the towers, and even cursed the Lion Sword - yet the Prince did not die.
Kaileena is also trying to defy her fate. She has seen hers in the
Timeline, which is to die at the hands of the Prince. Therefore, her
only concern is to get rid of him at any cost. Shahdee, feeling that her
mission to help save Kaileena was foolish, illogical, and futile, had
turned against her only to be killed by the Prince.
The Prince reluctantly fights and kills Kaileena. He returns to the
present, hoping that he has escaped his fate, but soon discovers that
when he killed Kaileena, the Sands of Time were spawned from her body.
Realising that he has caused the event he intended to prevent, the
Prince begins to lose hope, but soon discovers the Mask of the Wraith,
which is said to have the power to defy fate. When he puts on the mask,
he transforms into the Sand Wraith, the dark creature he saw earlier.
The time portals have a greater effect on him in this state, causing him
to relive the events of the past as the Wraith (and see his encounters
with the Wraith from the opposite perspective). When he reaches the
point at which the Wraith saved the Prince from the Dahaka, he instead
lets the Dahaka kill the "other" Prince, causing the mask to fall off
and him to return to the position he was in just before he entered the
Throne Room.
The Prince decides that he may he not be able to avoid killing Kaileena,
but if he kills her in the present rather than the past, the Sands will
not be created until after he had used them, thereby escaping his fate.
The Prince confronts Kaileena again and forces her through a time portal
into the present. At this point the ending forks, depending on whether
or not the Prince has found all of the health upgrades and acquired his
ultimate weapon, the Water Sword.
Without the Water Sword (Alternate Ending): The Prince and Kaileena
fight again. After the fight, the Dahaka appears, but ignores the Prince
and kills Kaileena (since she is now the one who is out of place in the
timeline). The Dahaka then heads for the Prince, but only to take his
Time Medallion. Having escaped his fate, the Prince sets sail for
Babylon.
With the Water Sword (True Ending): The Dahaka appears and heads for
Kaileena (since she is now the one who is out of place in the timeline).
However, the Prince discovers that the Dahaka has a weakness to his
Water Sword. The Prince and Kaileena fight the Dahaka together and
manage to defeat it. Having both escaped their fates, the Prince and
Kaileena set sail for Babylon together. (This is the ending that fits
with the sequel.)
