Thunder Throne Zone

Thunder Throne Zone is a Level in the Sonic the Hedgehog Series. It is the capital of the still forming Eggman Empire that Team Sonic needs to stop, and is the third level of Sonic Eclipse.

Description
Eggman has built a control tower that serves as the capital of his Empire that he is attempting to start. A giant storm plagues North Island while Team Sonic is here, though it slowly begins to improve as they leave.

History
Thunder Throne was originally a concept for a final level in the development of Sonic Eclipse. Once Panic Planet was drafted, however, Thunder Throne was scrapped. SEGA did decide to leave it in the game, however.

Trivia

 * The moon appears in Thunder Throne, despite the fact the entire game takes place during day (the darkness caused by the eclipse doesn’t count as night).
 * Concept screenshots show that Thunder Throne was going to take place during the daytime. This could possibly be related to the change of plans with the level.
