Now that all daimons are dead there's no reason whatsoever to join Ar Agyr. 
Daimonkilling was your Eifel Tower, your Niagra Falls. Imagine tourism ads for Niagra Falls (city) after Niagra Falls (waterfall) disappeard: "Come and visit Niagra Falls! Nothing to see here!"
"Come and join Ar Agyr to kill some Daimons! There are none of those left." 
You could join Ar Agyr for the hospitality and gold
Plus after the daimons are gone for good we are going to have to throw our soldiers towards something/someone, and nothing is better than going clubbing with a friendly bunch of Agyrians.
