So one of my friends whos char was a 13yr member of my current party passed away tonight. We were just about to start a huge arc revolving around his char and his weapon "The Crazy Hammer" I wrote 90% of it already. But now I think I'm going to rewrite it for us as a send off for his char. Then I'll be retiring it.
That's rough. My condolences to you, your group, and his family.
Before I share, I want to say that I'm definitely not trying to make your tragedy about me. My story is more about shared experiences.
That said, my current group also had someone pass about a year ago. He wasn't a close friend or had been a part of our campaign nearly as long as your friend, but he was well-liked by everyone, a fantastic player, and and passionate about D&D. He was also the only player that would really get into his character.
Occasionally, after our Thursday sessions he'd stick around in Discord and the two of us would chat about all kinds of D&D stuff. I distinctly remember two nights where I had to tell him I had to go because we had talked until after 2 a.m. (from 11 p.m.). Telling him I had to go was tough for me because I could tell the guy was incredibly lonely. He also very candid about himself. He told me that he was morbidly obese and that he needed to do something about it.
Anyway, at some point he vanished without a word, but none of us thought he'd abandon the group so we figured something serious must have happened and he'd be back eventually. After a month I got worried and started looking for him online. Fortunately, he did a few things for me in Googledocs which gave me a couple breadcrumbs to follow and I was able to learn his name and where he was from. That's how I found out that he'd died from heart failure.
I won't lie and say the other players were devastated, but his passing definitely bothered them and the group re-named the Inn they use as their base of operations in his honor.
Fair winds and following seas, adventurers.
