Vale(fictional Earth) is unaware of the danger of Death's awakening, so Life went to Vale in five human-like forms
Life seperated itself into 5, 4 of which are the elements Earth, Water, Fire, and Air
The 5th form is the Catalyst. Life only sent him to Vale when Death was near his awakening.
I'm hoping that this story will become like the Genesis of this universe I'm creating which is composed of other stories, too.
