I had never read the continuation of the Key to Time but apparently the writers have. I was searching the internet and came across 3 audio books that had been put to paper: The Judgement of Isskar, The Destroyer of Delights & The Chaos Pool. From these stories I gleaned more insight into the writers of Lost. Apparently they took elements of these stories along with the Key to Time and the Face of Evil took key plot lines shook them up and came up with Lost.
Excerpt from the Destroyer of Delights:
The Guardian’s deep booming voice changes to a more normal tone and he admits that because the segments are already outside time, they’re also beyond his reach. The Guardian is tired of the stereotypical negative image he normally projects and says there’s more to him than just that. He’s responsible for 50% of reality and he resents the fact that people think the White Guardian is nicer because he puts on a doddery old man act. He says the White Guardian represents law, bureaucracy and red-tape, whereas he is the opposite - but he argues that chaos isn’t bad in itself and it’s the variation that makes life interesting and adds colour.
I’m not saying that everything matches 100 percent but you don’t have to be a genius to see that these events are similar and when put together with the mounting stack of other similarities that I have found you would have to be pretty gullible to believe that this is still a coincidence.
