When they arrived at Senntisten, Saradomin and Armadyl found carnage which increased the deeper they went into the city. Demons, vampyres and humans were all being slaughtered for the sake of chaos, and their killers were celebrating the rise of Zamorak who had just ascended after defeating the Empty Lord. Then Saradomin turned to Armadyl and whispered,
"Armadyl, now we must work to bring peace and order to the world. Take the Staff back from them, I will entrust you with its protection. I will find the Stone when our business is finished on this empire."
Armadyl was shocked that after giving Saradomin his warning about the Stone, he still insisted on using its power.
"Will the dragonkin not bring destruction and chaos of their own? Saradomin, there is every chance that they may kill you - I have seen the decimation of Kethsi back on Abbinah. It is too dangerous!"
The god of wisdom replied to him in a calm tone,
"This has to be done, Armadyl, otherwise the carnage you see here will spill out over the universe, including Abbinah. Please, help me to bring light to the shadows here so that this world may know peace."
The two gods arrived at the Divine Palace, and found the body of the Empty Lord crumbling away into nothing. Mahjarrat, demons, vampyres and humans all circled around him, all in a state of shock. Then Armadyl picked up his Staff, and Saradomin called out in a thunderous voice,
"The Empire of the Empty Lord is no more. We have come to banish the new god Zamorak from this world, as punishment for daring to oppose us. And we have come to claim the Stone of Jas and the Staff of Armadyl, to prevent their use for evil. This is the decree of the Alliance of Light."
Then they both departed to a cave filled with energy, and Saradomin asked Armadyl to bring the aviansie to Gielinor, and wipe out the shadows that he spoke of. Thus began the Zarosian Extermination.
