Sol Emerald (IDW)

The Sol Emeralds are objects mentioned in the Sonic the Hedgehog comic series published by IDW Publishing. They are a set of seven emeralds of great power from Blaze's world and the inter-dimensional counterparts to the Chaos Emeralds. They are protected by their appointed guardian, Blaze the Cat.

Powers and traits
Possessing immense power, the Sol Emeralds have been noted by Sonic to hold the same properties as the Chaos Emeralds, except their powers are "fiery".

The Sol Emeralds appear to possess a degree of sentience, although they are not exactly "chatty". They also have a connection to, and an unspoken understanding with their guardian, who claims can “feel their will”.

History
For some time, the Sol Emeralds have been protected by their guardian, Blaze the Cat. Eventually though, the Sol Emeralds instructed Blaze to come to Sonic's world to help prevent a “terrible event” that would befall his world.

Etymology
"Sol" translates to "sun" in a variety of languages, like the Latin root word "sol", and is the origin of the word "solar." This means that the Sol Emeralds translate to "solar emeralds."

Trivia
