"Magic is good. But our guards cannot use the knowledge that Wigmold's spells would provide. They're not fast enough, not nimble enough. They don't know how to strike first, preemptively. We've rarely ordered them to do so. But they do know how to lock down the city, and guard it day and night, so that no one can pass by unnoticed – which would be even easier with more eyes and swords. I would choose Roham."
