White Fatalis' Schrade Kingdom Legend
 * White Fatalis' appears in the Schrade Kingdom to reclaim its throne during an eclipse that blocks out sun from the kingdom and wraps the kingdom in complete darkness.
 * This suggest that White Fatalis might've appeared in Schrade Kingdom before in the past and since its presence alone can attract other Origin Dragons, all three Fatalis Brethren(Black, Crimson, and White)might've attacked Schrade Kingdom together.
