So I was going through King's Quest Companion and something just hit me...
Note before I begin, in the case of the King's Quest Omnpedia we just assume sorcerer, enchanter, and Manannan are all seperate characters since there is nothing specific which explicitley states that they are the same character.
However in the King's Quest II novel it mentions that the evil enchanter in Kolyma was wearing the pointed hat that designated him a member of the
Magician's Guild. Also King Graham mentions that he thought that the enchanter might have been the same sorcerer he ran into during his search for three treasures of daventry.
In Alexander's account of his adventures during KQ3, he mentions manannan kept several of the pointed hats that designated him as member of the Magician's guild.
Could it be that Peter Spear was trying to weave a connection between the three Magician's we saw during the first three King's Quest games. Infact to the point that he may have been implying that they were all one and the same character?
It also should be noted that there is possible connection that the Sorcerer from KQ1 may have been the same one that stole the Magic Mirror in the first place.
It brings an interesting thought, that if they are the same character, that perhaps we have a different spin on why Manannan watched in glee as the dragon was heading towards Daventry, and also why he kidnapped Alexander.
If Mannanan had been trying to destroy Daventry for years, being the patient man that he was, he may have first made sure he had stolen the magic mirror so that they wouldn't be able to predict the coming of Dahlia, and False Dwarf.
Its stated in the companion that fall of Daventry was nigh, when Graham found the three treasures at the last possible moment.
He certainly would have been upset at Graham for recovering the mirror, and the other treasures. It would have been a setback to his plan to destroy the kingdom.
Several years later when Alexander was born, he found another chance to weaken the kingdom by taking its first born heir. He had taken slaves in the past, but this one was special not only would he enjoy destroying Daventry's rulership, but he would also have the enjoyment of playing with Graham's own son.
It is known that mysterious spell had been cast on the Magic Mirror to darken it so that it could not be used to get information. Could Manannan been behind the spell?
While neither Manannan nor Mordack released the Three-headed Dragon, its known from King's Quest 4 manual that he enjoyed the dragon's destruction of many kingdoms on its way to Daventry, as he had a hatred for humanity.
