In a Warhammer FRP campaign I was in, my character (an Araby mercenary) had spent seven or eight sessions gathering clues to find a lost ancient city where a lifetime of gold was hidden, the other PCs agreed to act as support and help him if he needed it. In the first encounter of the first day in travelling to where he thought the city was, he was shot in the head by a Skaven sniper and killed. The rest of the party went on to discover the city and got rich in the process. Bastards.
