Zindflo, along with Kixo and Nagatyu, was one of the richest Styrans of the 23rd century.
In 2267, Zindflo, along with the rest of his people, was converted into a biomagnetic recording, as was Styra itself. The criminal Anzar had his partner Allura steal the planet so he could ransom it to the Federation Council. When they refused to pay, Spock suggested that he have the wealthy Styrans pay instead.
