Origin

A race once called the M'Kraan, the now Scy'ar Tal formerly inhabited a planet that held the M'Kraan Crystal, and thus the former connection. Until the Shi'ar destroyed their plant and claimed the M'Kraan Crystal for themselves. Survivors of the planets destruction, and their leader, The Eldest, thus swearing revenge on the Shi'ar and now set to seeking retribution. They adopted a new name for themselves, as the Scy'ar Tal, which translates in their tongue, to "Death to the Shi'ar". They are a hive mind race, and are led by The Eldest. A title that is passed down.

Powers and Abilities 

The Scy'ar Tal are a strong and aggressive warrior species, with the ability to  communicate and interact with each other telepathically, and with the ability to produce a blue flame like energy blast. The Eldest of the Scy'ar Tal can call on energy from the collective Scy'ar Tal, greatly augmenting his strength to such an extent that he could break the wrist of the Shi'ar Imperial Guardsman Gladiator, and increase durability to contend with the energy manipulator Vulcan.
