One of my main characters represents the strength of the group(toughness bravery etc). Another represents the mind(thoughfulness, wisdom and so on). The next repsresents the heart(passion, good cause and stuff). The last is the unknown(change, growth, you know).
I want something with four to them like seasons or elements. I thought of having elements with Earth's Strength but I can't figure out the rest. So can anyone help me?
