It's a PV script for MM(A game project I tried to make). And of course it's voice-over. I planned to do all the voice-overs myself and use a voice-changing program to create different characters. 

???:

The tower... 

For centuries, they have risen from the earth, unbidden and ominous.

In their wake, desolation follows.

Castles crumble, fields are scorched, and the very earth withers.

Wandering trader:

...Yet, when a princess from a neighboring realm is offered as a sacrifice, or captured in their raids, the tide of their encroaching may recede for a time.

Old gentleman:

...I heard it from my grandfather. In the long past, a gallant hero would rise in such dire moments. He would vanquish those fiends, slay their lord, and and restore peace.

But I have not witnessed such a man in all my whole life.

Disabled soldier:

...I curse my weakness. So many fine lads have marched off to face them, yet precious few have returned.

A crazy tramp:

The world is doomed!

No one shall survive! No one!

???:

...Unless, of course... You are the chosen one.

Seems great! So classicial plots! (Maybe the project MM is also a magictower-like RPG?)

By the way, how about making voice-overs with the help of AI?

WOW, great

It sounds good, like traditional hero stories
