Brog the Stoop was the most interesting character I have ever played. Half animal, half vegetable, half mineral, half insect, half biocomputer, half nuclear reactor chamber, half sane. He made a great addition to the party, and when he died, made a great addition to Mother Nature, in the form of half a ton of ashes, which GeltCarl used to fertilise her garden. He died so that another member of the party could survive. The fact that he knew that person to be an assassin after the wizard was beside the point. Brog was a Stoop, and as such, had to save another's life.
Last words:Chhtrripp. (He had an insectesoid throat, so his grasp of the Common tongue was always a little shaky.) It is possible that the last word were instructions as to how to bring him back to life by rebooting the biocomputer, but only GeltCarl understood them, and she ain't telling.
