Krona and his new army are able to murder some of the Guardians, along with some of the Green Lantern Corps during their first attempts, and they are also able to destroy the Central Power Battery of Oa, preventing any of the surviving Lanterns from recharging their rings. Wanting this universe as his own, Nekron recreates Krona as a being of immense power and sends him along with an army of similarly empowered spirits to kill the Guardians of the Universe so their immortal energies will tear the rift between the two realms wider and allow Nekron to travel between the two. The tear allows Nekron to see into the universe of the living, but is not big enough for a being as powerful as Nekron to pass through. The paradox is caused by an immortal being like Krona occupying a realm meant for the dead, which results in Krona's immortal energies leaving a tear in the time and space between the mortal universe and Nekron's realm. This results in a paradox that Nekron uses to his benefit. When the rogue Maltusian scientist Krona is banished by his brethren and trapped in energy form, he somehow reaches Nekron's realm. Since Nekron receives power from the souls who inhabit his realm, he is constantly trying to obtain more. His realm serves as a place where the departed souls of all who have died await passage to their final destination, good or bad. Nekron is the ruler of a dimension that borders Hell, Limbo and Purgatory.
