Work on the story began in October 1999, and took longer than expected. The team estimated two months, but soon realised they lacked the necessary skills to meet this deadline. Bullfrog's James Leach, who had previously worked on titles such as "Dungeon Keeper" and "Theme Hospital", was recruited, and wrote many challenges, all the dialogue, and enabled the team to make the advisers characters rather than just sources of information. The idea to make the advisers characters came from Alex Evans, who wanted them to interact with their lips synchronised. A system was developed that moved their mouths into common phoneme shapes, used as a basis to turn them into graphic equalisers that move into shapes according to the sounds being played. This facilitated localisation, as the game was to be translated into fifteen languages. Both advisers were voiced by Marc Silk, cutting the recording time by roughly half. The initial designs were produced by artist Christian Bravery, but these were considered too similar to classic devils and angels. Healey redesigned the angel to be more like a fairy. He was accused of putting his girlfriend into the game, something which he agreed with on reflection: he admitted that it looked "rather a lot like her". He then designed an old man resembling a cross between a hippy, a yogi, and a "kindly old man". The advisers' animations and emotions were triggered by keywords in the script document, a Microsoft Excel file consisting of several thousand lines. Much of the script was for the advisers, as they were to comment on everything happening as well as the other things players may want to do.
