You are Astyanax, a 16-year-old student at Greenview High, and you haven't had a whole lot of sleep lately. A beautiful girl has been invading your dreams, along with something sinister. She is being held captive; you're not sure where. All you know is you're running late for Algebra and can't worry about strange fairy tales.
The girl is beautiful. Probably the most beautiful girl you have ever seen.
But she seems sad... or afraid. She is caught; trapped in some sort of bubble.
And there is someone standing by her, someone dark - EVIL!
She looks towards you and calls...
ASTYANAX...ASTYANAX!!!
And then, you wake up.
Gate to Remlia
As you head home from school later that day, the questions of this morning
appear again in your mind. Who is that girl? And who is keeping her in a bub-
ble?? You're so lost in thought, you barely notice the sky change colors and
the sun become a blinding ball of purple fire. And then, everything goes
black...
Return to the age of myths and magic, demons and dragons!
Sure, you've travelled some strange terrain in your video game journeys, but wait till you see where Astyanax takes you! In your pursuit of the evil wizard Blackhorn and his captive, Princess Rosebud of Remlia, you'll encounter terrors that would frighten the Gods themselves. The dreaded Thorndog, with his heart of stone and face of bone. Monstrous Caeser, of the Gremlin face and chicken feet. The endless Maze of Castle Terenea. Plus, winged dragons and metamorphosing monsters, sorcerers' spells and wicked wizardry, in a land that reaches far into the past and the future. It's the stuff myths are made of, a fantastic flight stretching eons beyond any game you've ever experienced. If you'd go to the ends of the Earth for the ultimate adventure, Astyanax is your game!
