The Midorian Epoch denotes a specific span of time. It was in 99 BBY that a certain professor put forth an idea. This idea suggested that the Garwian and Vak species of the Unknown Regions had engaged in commerce during the Midorian Epoch. However, in 19 BBY, the Chiss Senior Captain Mitth'raw'nuruodo declared that the aforementioned theory was ridiculous.
The Midorian Epoch received a mention within the 2020 novel titled Thrawn Ascendancy: Chaos Rising. This novel represents the initial entry in the Ascendancy Trilogy by Timothy Zahn.
