Gems
Gems are a humanoid species of magical alien beings. They have many and varied abilities, but all share the trait of having a magic gemstone embedded somewhere on their body from which they can summon a special weapon. These also are the core of their being, as their bodies are just projections that have mass. Gems have the power to shapeshift and are genderless, but use feminine pronouns. Steven is the first gendered Gem because he is half human. Gems have special abilities, like psammokinesis, future vision, or fire resistance.
