Princess Blaze, the ruler of the Sol Empire, at work.

The Sol Empire (ソル皇国[1] Soru kōkoku?) is a political body that appears in the Sonic the Hedgehog series. It is a kingdom[2] in Blaze's world that is ruled by Blaze the Cat.


Not much has been revealed about the Sol Empire. Despite being called an empire, it is referred to as a "kingdom" and is ruled by a royal family.[2] This family rules from a castle and deals with public affairs.[1] They also safeguard the Jeweled Scepter, a powerful ancient treasure of the Sol Empire.[2][3] It is also the duty of the Sol Empire's princess to protect the Sol Emeralds, which are relics of nearly unlimited power.[4]



For some time, Blaze the Cat has ruled the Sol Empire as its princess. When she assumed her mantle as a princess, she also became the protector of the Sol Emeralds.[4]

Sonic Rush series

Sonic Rush

In Sonic Rush, the Sol Empire's Sol Emeralds got stolen by Dr. Eggman and brought to Sonic's world. Fortunately, Blaze got them back before the Sol Emeralds' absence led to the destruction of the dimension.

Sonic Rush Adventure

In Sonic Rush Adventure, the Sol Empire had its prized Jeweled Scepter retrieved from Captain Whisker and his crew, only for it to be stolen again by Dr. Eggman and Eggman Nega. When the villains later harnessed the Power of the Stars with the scepter, Eggman Nega threatened to destroy the Sol Empire with that power. Fortunately, he was stopped by Sonic and Blaze.
