What makes you believe that they won't play the role of the dissembler? Offer hospitality in the morn and then flay you when the sun sets for your shard? Perhaps leave you to the carrion eaters once their prize has been secured.

The ones who've held these secrets have done so for thousand of years. What, pray tell, do you believe you have to offer them that they have not already been offered?

Prepare as you have been. Read between the lines, find the answer you know is there. Prepare your emotions, and think of something in your memory. Think of something that reminds you of home. Hold onto it, remember it vividly. Keep it. You'll need it.
