“I have a list of Halo stories I never got a chance to tell. And at the top of this list has long been: Whatever happened to the Shipmaster aka the Half Jaw aka Rtas ‘Vadum? Homer’s Odyssey is one of my favorite tales, and I always imagined that Rtas’s fate after Halo 3 might be a little like Odysseus's after the Trojan War. Which is to say: What if our war-weary Half Jaw hero only got a brief glimpse of Sanghelios before he was carried away by the winds of some new crisis? How would Rtas 'Vadum find a new way home?

	“After I combined this idea with another that’s been kicking around my head for years—What if there was a San’Shyuum powerful enough to best a Spartan in single combat?—my Odysseus had his antagonist. And things just kept rolling from there. I hope Shadow of Intent gives Halo fans deeper insight into familiar characters and places while also raising new and exciting possibilities for future stories. After all, for Rtas ‘Vadum, it’s still a long way home.” - Joseph Staten
