BELOW THERE BE SPOILERS! This is the dialogue as collected on the Beta server with a good aligned character.
Field Marshal Vishra says to you, "I cannot emphasize the importance of your find enough, Cyliena. This could be the boon that we have been needing!" You say to Field Marshal Vishra, "What do you mean?" Field Marshal Vishra says to you, "I dare not explain it, yet. I must first request a council with Queen Antonia and the Overlord, and then... Well, let's focus on them first." You say to Field Marshal Vishra, "Can I help?" Field Marshal Vishra says to you, "Yes, we must make sure that the command tent is secure. Go speak with Buildmaster Angor. He will know what is needed." You say to Field Marshal Vishra, "Right away."
You say, "Hail, Buildmaster Angor" Buildmaster Angor says to you, "Still running around Scarstone, eh, Cyliena?" You say to Buildmaster Angor, "Yeah. I've been helping Field Marshal Vishra." Buildmaster Angor says to you, "The Field Marshal? Why didn't you say so!? Don't let me keep you then!" You say to Buildmaster Angor, "Actually, I've come for your help. We need to make sure that the command tent is secure." Buildmaster Angor says to you, "Oh! We'll want to do a sweep of the exterior, and set up some arcane shields against sound and sight based spying." You say to Buildmaster Angor, "That sounds perfect, Angor." Buildmaster Angor says to you, "We should act quickly. I will prepare seclusion totems, while you obtain sylvan potion sacks from vexed forest watchers." You say to Buildmaster Angor, "The dragonfly fairies around Hawkeye Trails?" Buildmaster Angor says to you, "Yes. By the time you have the potion sacks, the totems will be placed around the command tent. Apply the potions to them and the shield will be in place." You say to Buildmaster Angor, "I'll get right on it!"
