Aurben

The Marketplace
If you try to talk to him while at level or lower, he will reply:
 * Aurben: I have nothing for you now. Perhaps you can be of service when you're more powerful.

If you are at level or higher, however, he will reply:
 * Aurben: I have need of skilled adventurers and you look like you might do. Are you willing to risk much and travel far to help protect your kind?  You will be amply rewarded.  Even better, you will earn the gratitude of the dragons of Argonnessen.

Talking to him after acquiring the quest, but before completion, will make him say:
 * Aurben: I have instructed Captain Agamon to ferry you to Siber Atoll. He waits atop Falconer's Spire here in the Marketplace.

On completion of quest, he will congratulate you with the following:
 * Aurben: ????????????????

After completing the quest and taking the reward, if you talk to him again, he will reply:
 * Aurben: ????????????????
