Penelope

Penelope is the Aspect of thermal energy. They tend to be weaker at close range due to accidentally freezing the air inside their own lungs when they were young. Prefers to either only do extremely small tweaks to air in their proximity, instead sending these small tweaks out as almost a telephone line to perform large powerful tweaks at their destination. They also will channel tweaks closer to them on solid objects, as they are much more predictable than gasses. 

beyond here is still in the works :3

maybe they accidentally froze/killed their friends as a child when first manifesting their influence resulting in them believing aspects should be feared and generally being more pessimistic. they could choose to work with the group because cebba inspires them as to what aspects can be.
