On one side of the board.
Kristen Marx and Nayora Sharp, my 2 characters with the most development to them.
Marx is the first pilot to take an Elemental out of the testing grounds and onto the battlefield. Becomes and remains field commander of the program for her military career.
Sharp comes in a bit later, so they wouldn't be seen with similar ages like this. Like many other later Elementals she develops some very unique skills.
I didn't sketch these two side by side so their proportion styles vary a bit.
