The Queen Shows Her Face

Note: This is the official answer to the riddle: I Am the Queen - Guest Riddle from Deimos Tel`Arin

Dear friends of old, it’s been a while… As good old Gandalf would put it, I was… delayed.

Our friend Deimos gives us the final answer to the riddle he posted here a while ago, entitled I Am the Queen.

Here’s the solution, and of course the details of the contest can be found on his domain.

I am the Queen
She is someone with great power and authority.

I do not exist, yet many have known me for almost a decade.
She is a fictional character that has been around for almost a decade.

About the past, I was once good. Very evil, totally brutal I am now.
She was good, but now she is bad.

Mentioned within the Demon’s domain, I was.
This is a reference to Deimos’s domain ahkong.net as Deimos Tel`Arin fancies himself as a Cyber Demon. The Demon’s domain basically means Deimos’s domain @ ahkong.net

The queen is mentioned in this post found in Deimos’s domain:
Alien in your back yard!!

Sharp and pointy objects, my title rhymes with.
Her title is “Queen of Blades” and “Blades” rhymes with sharp and pointy objects, right?

An actor as a protagonist in a popular TV series shares my name.
Now who might that female actor be?

Revered for vanquishing beings that are dead yet not quite dead, she is.
Referring to - Buffy, the Vampire Slayer.

Also, her physical beauty quite matches with my own.
Sarah Michelle Gellar is quite beautiful, aye?

Hell be damned, now tell me - Who am I?
Just a filler text so that when the first characters of each sentence forms the following hidden (quite obvious actually) message reads - I AM SARAH

So yes, our Queen is indeed - Sarah Kerrigan, The Queen of Blades. Congrats to Wan Kong Yew for getting it correct, as well as Lis and roel for affirming it!

The date 1 April 2008 was chosen to be the date to publish the answers, as a tribute to StarCraft’s 10th year anniversary as the PC Game was released on 1 April 1998.

I wanted to thank Deimos for delighting us with this riddle and for taking the time to organize the contest!
