ok how do i explain it so they're basically two people sharing a body, but it's actually only one person so basically one person with two consciousness's gravita is calm and collected and impulse is aggressive and chaotic basically they take control of the body while the other acts as a spirit beside them that can still speak, that only the person controlling can see and hear so they can talk to eachother while only one person is controlling basically talking to themself but like not gravita has some good melee fighting skills and impulse basically has the power of the roaring knight also they can join forces so its basically a combination of their skills but better
