REALM 4 Trailer
They are first seen when an Employer resembling the Auditor flies up to join the rest of them. Ra then steps forward and takes notice of how Sokar had turned the color of the sky from red to purple. He summons a black flame with his hand and sends three of them down before the rest head off.
While overlooking Kelzad and Sokar's fight, Ra is approached by Osiris, who informs him that Sokar has conquered Nevada and urges him to take action before he "returns". However, Ra assures his subordinate that they have thrown him away from their realm before and decides to see if Kelzad can stand a chance against him.
Later, after Kelzad weakens Sokar, one of the Employers states they should interfere. However, Ra decides to hold off, believing Kelzad can take care of him, instead stating they should take back what is their's.
More to come.
