I'd be a wise, well-travelled fellow who had mastered Time Magic, carried a pair of wax nunchucks (really just a pair of candles joined at the wick) and I'd basically hang around with the party giving them advice on certain monsters before dying offscreen to stop a boss that they weren't yet supposed to fight from destroying them.

And of course, dying offscreen means I don't die at all, but show up later with barely a scratch and don't rejoin the party, but do the odd thing to move the plot along and then get forgotten about.

Now where's that FF6 spritesheet I did in my image all those years ago...
