@Tavie- they would be, it seems, if the Palace leaves the planet- since they would have to travel with it, within the scope of its aura. So if it went galavanting through the stars... the immortal elves could not stay with the abode, while the mortal ones could. @insaneland- that's an interesting idea. Maybe so. In that case, the above statement I just made could be modified by- unless a piece of the Palace stayed on the planet.
