Argus.
This means a giant red ball is argus' soul right?
then....what is this? What is this thing lingering on Seat of the Pantheon?
this is also the World-soul of argus, eh? And Titan used the argus' soul to imprison Sargeras.
there are two argus' souls?
Or red ball is just remains, echo of argus? Not a titan's soul? Then how does this ball get to the arbiter?
