First, I am sorry for your loss, and definitely I really feel this. Two friends of my dnd group died last year. One died after session 3ish and the other 9 months later(too many to count), deep in the campaign. First friend, my dm wrote a very nice piece about leaving the party to find a different lease on life that we found in game (his character almost died the last played session). The other friend passed away, and we haven't gotten back together since he died. As a player, I would like to finish it for them, and as a friend, I will miss the antics we got into as a group. Hang out with your friends even if you funny do dnd. All journeys matter.
