In a universe on the edge of reality in an astral plain that was never meant to fly, The Discworld flies through the cosmos on the back of four giant elephants that in turn stand on the back of Great A'Tuin the world turtle. Philosophers on the Disc are constantly trying to find out what it is the Giant turtle actually thinks about and it was uncertain what the Turtle was thinking when for no apparent reason the Great Turtle who since the creation of the multverse had plodded continuously through the universe-1 stopped.
In the huge city of Ankh-Morpork more famous more for it smell than its size, a wave of bright octarine flooded through the city noticed only by those individuals of a magical persuasion. By a freak chance as the wave of light past the palace, the Patrician of Ankh-Morpork looked up through the window of the oblong office into the teeming street outside the palace-2 and sighed "Damn wizards" he said as he was about to yell for his messenger but then he remembered the new invention of Leonard's he had want to try out. The patrician reached under his desk that was piled high with the latest spy report from the thieves and assassins guilds and pressed one of the three rather small green buttons concealed under it the three buttons each had little labels under them they read.
: 1.WATCH.
: 2. ROBERTSON-3.
: 3 WIZARDS.
He pressed the third one. "Somebody better have a good explanation for this" he said under his breath.
When the Patrician had pressed the small green button it had turned a light on in a small compartment in his desk which woke up a rather large overfed imp. The imp climbed out of bed grumpily and walked over to his door and opened it, it led into a giant4 rubber tube. The tube was connected to what Leonard de Quirm called "A large metal tube you speak into to make sound travel better" device on the patricians desk and the tube split in three at one point one led to unseen university, one to Robertson's office, and another to the main watchhouse. When the Imp reached the main tube he yelled "One second, trying to connect you" then the imp walked along the wire until it split into three where he pulled across two rubber slides blocking the tubes leading to the watchhouse and Robinsons office. "Your connected" yelled the imp.
The Patrician picked up Leonard's device, he was quite exited to se if it would work it could become very useful. He spoke into one cup shaped object holding the other one to his ear and said "Come here Ridcully, I need you."
1-For no apparent reason
2- The patrician of Ankh had recently realised he wasn't playing fair all the other kingdoms had a leader and then the 2nd in command/deputy/Grand adviser who sole purpose appeared to be to try to double cross the King/Emperor/Commander to try to get his job so the patrician had made the new post of deputy patrician and in the last three months he had had more than twenty deputy patricians Robinson was the latest
3- Some people never learn
4- From the imp's perspective
5- The patrician had been taught at the assassins guild and all assassins learnt to see into the octarine what you couldn't see could kill you.
