(Mortas Confronts Player) Fellow Mortal. Join me or die. I shall soon rise and become immortal, I will make a new world. Everlasting darkness shall reign supreme. All who refuse to join me will be crushed to smithereens.

Player: Who are you? Are you working for Namira's Cult?

Mortas: Namira's Cult work for me. I'm the royal prince of Athena but I grew tired of playing the game of thrones. I didn't want to be like my father. I want to be the opposite, I saw so much suffering in Athena. My heart turned to stone.

Player: There is still hope, turn from you're foolish ways.

Mortas: It's too late, I have formed the black alliance.

Player: What's the black alliance?

Mortas: It's a dark alliance, the most evil guilds are working together now,  it's an alliance between Namira's Cult, the Sinistral Elves and the Red Sabre Pirates. They might have their personal plans for their guild, but they ultimately work for me now. I promised them great power and coin.

Player: You're heading to destruction, I refuse to join you.

Mortas: Fool! Then you shall die!

(Uses his power on the player, player wakes up in a prison cell.)

(Last Encounter with Mortas)

(Player enters a secret portal to Oblivion)

(Mortas confronts Player) I'm here to end you. You killed the leader of Namira's Cult. You killed my friend Avalon and nearly annilated the entire race of elves on this Island, and you also killed Captain Jack. You have destroyed the Black Alliance, and now I'm here to destroy you.

Player: Their days were numbered and now I shall kill you.

Mortas: I should of killed you when I had the chance, taste the string of death now mortal.
