Thankfully, I will not have to resort to AI, at least for Palpatine’s new dialogue. Someone has reached out to me who can voice act Palpatine.

Here are the new lines I’m planning:
“He had such a knowledge of the dark side, he could even keep himself and his apprentice from dying.”
“Unfortunately, he taught his apprentice everything he knew, then his apprentice killed him in his sleep before he could heal himself.”
“Learn to know the dark side of the Force, and you will be able to unlock Plagueis’ secret to cheat death.”
“I know you’ve always craved the power of eternal life, to deny death, just as much as I do. It is only natural. We must conquer the Jedi Temple, take back the Sith holocrons they have kept from us. Use what we can. With our powers combined, I know we can unlock Plagueis’ secret. If he could discover the secret, certainly the son of the Force itself could.”
“Together we will rule the galaxy forever. Me as Emperor, and you as my invincible enforcer. You will answer to no one but me, son.”
“Know the power of the dark side. The power of eternal life.”
“Every single Jedi, including your friend Obi-Wan Kenobi, are now enemies of our new Empire.”
“Only then will you be strong enough with the dark side to cheat death.”
“Once more the Sith will rule the galaxy… forever.”
