Greyfox said: "Does one with our shared blood walk with you?" I thought that meant is Tyldak there with you.. But then again, Tyldak and Kahvi don't share blood, as I recall
I actually thought he meant Tyldak first, although I also didn't get the "shared blood" thing - because I figured it would be natural for Windkin to be asking about his father/pal that he hung out with for howevermany thousands of years.
But he knows Tyldak is dead, so why would he question whether his spirit walks with Kahvi in the Palace?
I guess it's ambiguous, it could mean, "Is Tyldak there and are your spirits hanging out together, or is he off doing his own thing elsewhere in the giant sphere of Palace magic?"
But that seems a bit of a stretch. It makes more sense to me, now that @Mkal and @travelbug suggest it, that he would be asking about someone else, to see whether or not they're alive.
