Re: OOC
That is a very good question.
Babylon 5, the best TV show ever 30 years ago, had very good explanations for every long-term character that left the show. The West Wing, which started after B5 ended and tied as best TV show ever, did that for some of their long-term characters, but for others they did nothing. Never referring to the character again after they had left the show.
The latter is obviously the easier option, especially for when Keliantharas returns. And it fits with how I generally treat characters in combat if their players aren't posting.
So I wasn't planning on explaining his absence. And in the same way, I wasn't planning on explaining him showing up again when Real Life calms down for him.
Depending on how long that takes, some players may find it insurmountable to come back to a game after being away from the game for a long time. While others have no problem at all. So we'll see how it goes.
In some cases, I find a way for the character to die, which isn't appropriate in this case.
