Kreia (aka Darth Traya):
Kreia is from Knights of the Old Republic II: The Sith Lords and is an older
woman who sort of acts as a wise master figure to the player's character known as
the Jedi Exile. Later in the game it's discovered that Kreia was once a Jedi but
just like what had happened with Revan and Malak, Kreia traveled to Malachor V and
was seduced by the Dark Side becoming Darth Traya.
Following the Jedi Civil War, Traya sought out other would-be Sith and discovered the
men who would become Darth Nihilus and Darth Sion. However, as always, the two
apprentices bretrayed their master and stripped her of her connection to the Force.
Much later Traya took back the name of Kreia and found the Jedi Exile - convincing
he/she to gather three Jedi Masters who she then kills - revealing her Sith loyalties
to the Exile. Eventually, the Exile hunts down and kills Traya.
Silk Fox (aka Sun Lian):
Silk Fox is the young female assassin in Jade Empire. Very little is known about her
until she reveals herself to be Princess Sun Lian: the daughter of the Emperor. Concerned
about her father's change in character and his actions, Sun Lian blamed the rise of
the Lotus Assassins and Death's Hand. In an attempt to possibly correct her father's
wrongs and discover what changed him, Sun Lian became Silk Fox and traveled the
Empire looking for clues.
Saren Arterius:
Saren is the main antagonist in the first Mass Effect title. Being one of the longest
serving Turian members of the Spectres, Saren is highly respected and even feared by
most of the universe that knows his name, and for good reason. Unfortunately, Saren
goes rogue when he comes into contact with the Reaper known as Sovereign and is quickly
indoctrinated under its control.
For most of the game the player finds themselves wading through Saren's geth attacks
while trying to track him down and stop him. Eventually, Shepard confronts him on
the Citadel and defeats him
Dog (aka....whatever the player names him):
Dog is...well...a dog that acts as a team member in Dragon Age: Origins. Usually
obtained at the beginning of the game, Dog (or whatever the player chooses to name it)
is one of your very first companions. Being a Mabari War Hound, Dog is fairly powerful
and can do some real damage to the enemy when used properly. While obviously there is
no true dialouge with Dog the player can still interact with him by petting him, feeding
him, and giving him gifts like different kinds of bones.
There's nothing like man's best friend...
