The world of Domhan has been at war for many hundreds of years. In that time span, some Veikas, children of Ako, have lost their lives. Nobody knows what happened to the souls of said Veikas, but their bodies were utterly destroyed. Some say that the soul of a dead Veika will seek the body of a worthy Emberi to inhabit, so that they may be reborn later. The death of a Veika does not imply the death of the concepts given to them. For example, if Rastlin were to lose his life, nature would not suddenly wither and die, never to recover until (or if) he is reborn. Instead, it implies that the associated concepts are now in a state of chaos; with no one to rule over them, all are free to manipulate them and interact with them as they wish. Any "rules" that a Veika may have wished to maintain would be null and void and, so far, no Veika has ever claimed any natural force previously associated to a dead Veika.
