Condolences on your loss, Photon Wyvern. With the passage of enough time, your good memories of your grandfather will be only slightly tinged with sadness. I truly believe that when each of us shuffles off this mortal coil at their appointed hour, we are forever with those we were closest to.
We will welcome you back to Istaria when you are ready to return. Take care, and may God bless and comfort you.
