Alistair was being risky. His safety was the biggest concern as he left their current stronghold in Scotland but it was necessary. This risk was necessary. With the Crown fretting about at the Palace for Bri's wedding day, now was the best time to make a move and get the word out to his people. His patronus went out the day before around 11pm and his guards, those guards that he had inherited from Trip who would do anything for Alistair, were set to arm the castle that he called his people to with enough wards and enchantments that would put the Palace to shame.
Once everyone was assembled, Alistair delivered an eloquent speech. He reminded his people that he was untested. He gave them the opportunity to leave if they so desired. Alistair expressed his commitment to his country and to the people who lived within it. All people who resided within. Merchants and nobles alike. He reminded those, especially the nobles, that were there that the caste system was employed by his grandfather and the nation was not always ran this way. That the reality of their position left room for people with great talents to go to waste for no reason other than who they were born to and that that reality would no longer exist in the future he saw. Empowering those of all walks of life would be the only way they could rise up and defeat the Empress once and for all. How were they able to defeat a person with such darkness in her heart when the darkness in the country mirrored hers in every way?
At the end of the meeting, he gave everyone a choice. Alistair cast a very specific form of protego diabolica, the black flames not only protecting him but surrounding him in a 30 foot circle. The parameters were simple: if you supported Alistair or his mission to regain control of the crown without hesitation or doubt, you would pass through the flame without harm. He did not require you to walk through the flame but stated if you didn't, you would be obliviated. Three nobles left, promptly caught by his guards and obliviated and sent on their way. One person crossed the flames with nefarious intent, burning to cinder and ash before their very eyes. Once inside the circle, a charmed galleon was given to those who proved their loyalty with the reminder that he would reach out the next time he would need them.
