This is terrible... and he had a FFXIV avatar too. I remember his posts were usually short and to the point, but always intelligent. ; ;
Rest peacefully Serge. You will be deeply missed.
Did you happen to know what server he played on?
If he was on Balmung, I could try to contact his FC mates and let them know if they don't already.
Sadly I have no idea - I even tried looking back through this thread only to come up empty handed as it appears he never posted his character details in there unfortunately. ; ; It's possible he might have stopped playing a while ago but just kept his avatar. Oh well.
If his character still exists though, it's his legacy (or one of them).
