Merlin

Merlin is an all powerful entity who created The Crimson Valley. From the beginning, it was he who controlled everything that happened in The Chronicles Of The Sea Of Dimensions.

Origins
It is said that there is a castle at the end of reality. This castle is dominated by a group of wizards called Strangers. According to legend, Merlin was one of these wizards who went rogue and created The Crimson Valley. From that point on he controlled the events in his world, including the destruction of The Crimson Valley and the creation of The Sea Of Dimensions.

Time Paradox
When Bob realises that he has caused a time paradox, he does not know that this is exactly what Merlin intended. Seeing as Merlin controls everything that happens in The Sea Of Dimensions, he decided that he did not want Ragnarök to happen for a while yet, seeing as meddling with reality is quite fun.

Unfortunately, before he could solve the time paradox, the Strangers caught up with him and arrested him for breaking the laws of time and space. This meant that no-one was left to solve the time paradox.
