[13] The Tome of Divinity - Part 6?:

Retrieve a Defias Script from the Defias Wizards in Elwynn, and return to Gazin Tenorm in Stormwind.

We'll have time to talk more about the Symbol at a later time. What's important now is to get those papers we saw the Defias going over. If we can get our hands on them, we'll be able to prove the Defias have infiltrated Elwynn and hopefully gain some insight into what their plans are.

I'm in no shape for battle as of now, Tinglie. Do you think you're strong enough to get those papers from the Defias here on the island?

If you're able to get them, bring them back to Gazin and let him know I'm all right.

High Priestess Laurena: Is Henze safe, Thorson? Were you successful?

Between your skill with a weapon, and the power of the Light, I'd imagine Heroes' Vigil is safe from any Defias threat, but that's for the King and his advisors to say.

High Priestess Laurena: Wonderful! You made it, and saved Henze. The Light is with you for sure, Thorson!
