All the members of the Demonic Sect Alliance have left the headquarters, leaving only me and Jerome inside his villa. All of them were off to find more members for the Demonic Sect Alliance specifically first-rate demonic sect masters.
The only requirement for joining the Demonic Sect Alliance was that the member must be a first-rate demonic sect master and if he or she isn't, then he or she has no chance of joining the Demonic Sect Alliance.
I might allow beings other than first-rate demonic sect masters into the Demonic Sect Alliance in the future, but only after I have stabilized the Demonic Sect Alliance. But even shortly, I won't allow any beings that are part of the righteous side to join the Demonic Sect Alliance.
I will allow demonic mages and other beings as long as they are either part of the demonic side and if he or she is useful, then I might allow it even if he or she is part of the neutral side but never the righteous side.
