Originally it was going to be 4 parts long, but on looking at it I decided that the original ending to the original episode one was superfluous to the story in the extreme, whereas the original episode 3 ending bridged episodes 3 and 4 with minimum of fuss, and could be removed.

The original episode 1 ended like this:

"en route to Egypt, Marson tells [the Doctor] of a meteorite that crashed, and how the new pyramid was found on the exact site. As they approach Egypt, and the site, a mad sand storm whips up, and the helicopter starts to go out of control

"Someone doesn't want us here!" "

Episode two was then to begin like this:

"The helicopter is trapped in a sand storm, and things are looking bleak for the Doctor and Naomi. However, Naomi manages to pull the helicopter into a tight dive, and lands safe enough."

In the final version, these two episodes make up the longer-than-normal episode 1, and the helicopter takes off and is seen to land safely, with no mention of the storm.

Episode 2 as it is, then, would originally have been episodes 3 and 4, the ending to episode 3 planned as being this:

"However, the four explorers (The Doctor, Jack, Naomi and Tiruphs) are a threat to the Sekonians (the skeletal "forgotten gods"), and the High Lord shouts "Now kill them, kill them all! The reign of the Sekonians is beginning!" "

The story ended as planned, with Toruphs self sacrifice to destroy the Sekonians and the pyramid, but the Doctor's final line, "I'd rather like to find my jacket", was originally "…I think I've had enough of pyramids for one day", as he breaks into a smile…
