Skyblock

This is the main setting of Chapter Four of Zisteau Plays Minecraft. It is underneath the Alpha Valley as of Disjunction, and consists of a small floating island within an area comparable to the unimplemented Sky Dimension of Minecraft. It is being played in Beta 1.8. It is generally foggy, except after Zisteau hides in the shelter due to the storm, which is when the fog clears.

Snowy Hill
This is an elevated, snowy area in the Sky Dimension, prominently featured in Enumerator and then in Thin Air, Cyclone, and Interloper.

Enumerator

The area is featured, with Zisteau walking towards the sunset, beyond a tree, each time the episode loops.

Thin Air

The next time the area is featured is in Thin Air, where it is seen at the end of the episode, with Zisteau walking towards the tree, saying "It looks like we jumped again" before the video "crashes", looping the same split-second section of video over and over again.

Cyclone/Interloper

The area is seen in the same scene as before each time the playthrough loops. This appears to be what causes the playthrough to loop, as the line "It looks like we jumped again" combined with the fact that this scene is shown when Enumerator loops hint at this location being prominent.

Skyblock Island
This is the small main island of Skyblock. Zisteau appears on this island in Whirlwind, and again twice in Cyclone and many times in Interloper, after the playthrough loops. The island is a classic Skyblock Survival island, with a grassy floating island containing several blocks of sand and 1 tree (with different type trees grown on top of it based on the saplings gathered in the previous playthrough), and a chest containing water, lava, sugarcane, cactus, melon, bones, etc. as well as the resources gathered in the previous playthrough.

Sky Dimension
This is the area where Zisteau spends most of his time in Thin Air. It consists of many large floating islands, with water, lava, and resources. This area seems to have a property which causes Zisteau to "jump" across gaps and to new parts of the world, also undoing progress the last time he "jumps" in a loop, which causes him to end up near a completely unmodified Skyblock island. It is assumed that this is the island that Zisteau restarts the loop on.

Trivia

 * It is assumed that the loops here and in Enumerator are the same, due to the snowy hill appearing in Enumerator, and there being path building in both, as well as some part of the previous playthrough carrying over between loops. (The world carrying over between loops of Enumerator, and the resources carrying over between loops of Skyblock).


 * This may take place inside of Zisteau's mind.
