So the meeting with Serana and Harken original would be something like,
"A Melabone, I thought your family died out ages ago with the death of your father," Harken.
"You would wish for such a thing," Eldire paused, "I brought back your daughter Serana. Though I feel what is worth to you is the Elder Scroll. If only the other families could see what you have been hiding."
"I'll be creating a better world for our kin," Harken.
"So you say," Eldire says, "But all I see is a family hidden in a tomb."
"How dare you insult my family, when your family is simply dust in the earth,"
"The Melabon are still alive, they may have weaken, but they still live. I ask Harken, what is it that you desire with the Elder Scrolls?"
"Aid me, and you shall find out. Forgive me if I don't trust enough family,"
"Afraid I'd take your reign?"
"Aren't you cheeky, so young, and fresh. But no you'd hardly match the power I have had, you are merely still a young fledgling compared to your father,"
"What if I refuse to assist you Harken?"
"We all know you coudn't refuse, you are after all the same as me. Come find me in the catacombs near the shrine of Molag our creator. We'll see how much you have learned from your father,"
