First, I would like to apologize for the cryptic note - but discretion is imperative.
As past events have taught us, others in the Horde may act without proper planning, or restraint. We plan to move first towards our next objective and avoid further pointless losses.
You have shown yourself to be a highly skilled and reliable ally. We would like to invite you to join us - as soon as possible - at the Valley of the Emperors in Kun-Lai Summit.
We hope you will meet us with all due haste.
-A Friend from Silvermoon
