Before the beginning of the war, the Light Trinity were those gods who preferred to lead the peoples gently, offering knowledge and wisdom where it was requested. Relations between the Light gods are peaceful - they each have their own area and work within them to better the whole. Equally, they are not territorial and wouldn't blink if another god strayed briefly into their sphere of influence.
The Light Trinity are all good-aligned, but have no other alignment component. Although they are not omnipresent, their age wisdom and power means they see the world differently from mortals so the concept of law vs chaos, whilst significant, doesn't mean the same thing amongst the heavens.
