The Eternity Gems

Name: The Power Gem
Tech, Magic, or Cosmic: Cosmic
Function:

Power Name: Energy Manipulation
Classification: Kinesis
Limitations: Dangerous for one to use, as it has a kickback equal to output on the user.
Description: The user can create, shape and manipulate energy, the capacity to cause change: one of the most basic quantitative properties of a system, such as an object or a field of energy. Energy can be transformed (converted) among a number of forms that may each manifest and be measurable in differing ways. The law of conservation of energy states that the (total) energy of a system can increase or decrease only by transferring it in or out of the system, thus the total energy of a system can be calculated by simple addition when it is composed of multiple non-interacting parts or has multiple distinct forms of energy.
Common physical forms of energy include the kinetic energy of a moving object, the radiant energy carried by light and other electromagnetic radiation, and various types of potential energy such as gravitational and elastic.

History: The Eternity Gems were created at the dawn of time. When there was nothing and then there was. When all life and matter came into existence, so too did the six most powerful artifacts known to the Universe. They are treated as a myth as it has been eons since they were last successfully held by any one being, even individually. They are powerful beyond belief and instantly make one who holds them into a cosmic being. Each is powerful in its own right, and can be difficult for normal beings of power to even hold one, much less be able to use it. The last time they were used, it was by a mighty being known as Xero. He placed all of the gems into a cube and used that cube to destroy the galaxy that he lived in. This galaxy simply ceased to exist, but the strain that using all of the gems together was too much for him to handle and his body disintegrated. Moments prior to this, he realized that the stones were too powerful if used together, so he used the last of his power to send the stones to different, far away planets.

Name: The Soul Gem
Tech, Magic, or Cosmic: Cosmic
Function:

Power Name: Soul Binding
Classification: Kinesis
Limitations: Takes a heavy toll on the users soul, and the only way to obtain it, is by trading a life, or a "soul for a soul".
Description: The user can manipulate the soul, the incorporeal and immortal essence of a living thing, souls are usually most obviously present in sentient beings. At some level all biological organisms have souls, and even non-biological entities (such as rivers and mountains) possess something that is analogous to a soul.
Most users have to learn to control their own soul first and expand from there, some may be able to learn how to tap into the essence of everything living.
Requirements: Must trade a Soul.
