I'm a team member of a non-commercial team called Spur Byte. We're going to use Wintermute Engine and add a speech pack, we're currently holding auditions now (we've decided to choose the roles ourselves from there). Our forum will be up soon, until then, please record the text below if you're interested and send it to ladydeloria@hotmail.com.
Thanks.

(says to the world and herself/himself) "It has been so long… I never dreamed I would see the light of day again. I am… free…
(emphasizes free) You shattered my prison… my gratitude is… beyond words.
(slight pause) My story is a… mournful one. I was buried alive in that marble long ago.
It was my retribution for attempting to break out of this land. If you do not wish to wind up like I did, have faith in no one. You are being incessantly watched and deceived by one, whose motives are sordid. May the heavens above favor you, valiant one."
EDIT: The person in question may be either male or female.
EDIT (2): Slight modifications: the auditions are for every role, not just that of the narrator.
