I can't believe I'm asking this, only I am, so then I do believe:

So. Licyn slipping in to visit Vataz's body. Is there any scent he'd pick up on that was different from a. normal ones for Vataz or b. anything related to body preservation should anything be used?

Look if you gave him Vataz to sleep with it's only fair he also has the worst reasons to know exactly how someone should smell when he's coming to give a sort of farewell and "... admittedly, not better you than me, but I'm sure glad to still be living."
