At the urgings of some of your fellows, you take another, closer look at the inside of the temple. It is much different from the way you remember it - Not structurally, but because there is no more feeling of oppresive evil, no guardians or traps placed to stop or kill you. One of the rooms has collapsed in on itself, and the place seems to be in disrepair, abandoned for some time.
You arrive at the place where you'd found the Lich's Phylactery, and you can all see it once more in your minds eye - Keira's holy avenger swinging down, the splintering wood, the faint scream of the lich, its soul released into the nether, and the satisfaction as you felt the unholy evil draining from it. There are no traces of it now, though. Not after so many years.
It is Verity who (again) first notices the difference. A message, carved into the stone. They'd missed it on their exit because they'd been facing away from it, but there it was plain as day, and centuries old...
"Thanks for freeing me from that rotten old bastard's grasp. Perhaps some day this will return the favour.

PS, I borrowed some of your stuff."
Beneath it, on a stone pedastal, is a large hourglass, untouched by the dust or cobwebs, it's sand has all filtered to the bottom.
