I know this to late, but it IS mentioned in the game manual, which you should have in a pdf file in your TOEE directory. Now that you know, you can go kick some froggy butt and storm the moathouse when your ready.
hmm, yes, the manual, i actually have the original leaflet in the box still, a bit ruffled but in good condition... I remember being amazed at how huge it was when i got the game, and spent quite a few hours reading it. Naturally, I understood nothing of it, which added to my amazement of the game, before shelving it
