No one present objected and all agreed.
First of all, the macaw, the Duke, and the elders of the moon Shadow Council were all on their side. Arthur had officially cleared his name from being an extremist and became an official partner. As for Ivan of the Brotherhood, he had agreed to it ten thousand times!
The Brotherhood's biggest enemy was the Academy.
the academy had captured various mutants for dissection research and had a mature team that specialized in dealing with mutants. The Brotherhood suffered heavy losses because of this, and it could be said that they hated it to the bone. the platinum hotel was in cahoots with the academy, and neither of them were good things.
Now that they were dealing with the two forces that were colluding, Ivan was in full support.
Moreover, he would only be able to take in the " homeless " mutated humans if he completely destroyed The Platinum Hotel and the Academy.
