Tuterian

The Tuterians were a space faring humanoid species from the Delta Quadrant.Its known that they had close ties with the Krenim Imperium for several years, which were still standing in the early 25th century. During the 2390s, the Borg threatened the Tuterian homeworld. To prevent themselves from being assimilated, the Tuterians used modified Solanae technology, successfully saving their home planet.

During the Vaadwaur Supremacy's attack on the Krenim Imperium, at least one Tuterian was in Kyana Prime when the Krenim used temporal technology to hide their cities by taking them out of the timestream.
