It didn't take long for Zatiel to arrive at the location where he will build his tower since it was less than two hundred kilometers from the Underground entrance.
Zatiel had decided on this location for a simple reason; it will allow him to grow the number of individuals under him at a fast rate since he was planning to accept anyone despite whatever race they could belong to.
Of course, no matter how strong they are, they will only be peripherical members of the tower at the beginning, and they will be under constant surveillance, which will work to detect those worthy of nourishing and those that should be removed.
Although this tower will not be much of an enticement for most Magus since they could go to the Sinux Magic Tower, where they will have the same opportunities and safer environment, those that Zatiel was hoping to obtain were not them, but those that are not accepted by the rest.
