Valiant has announced the new one-shot origin tale Harbinger: Faith #0 in December, which will correlate to the new story arc beginning in Unity #12 releasing in November.
 
Faith Herbert, aka Zephyr, is Unity’s newest team member, and after the events in Armor Hunters: Harbinger (see "'Armor Hunters' Is Valiant's 2014 Crossover Event" and "'Valiant First' Initiative Launches New Titles"), she need some time to recuperate.  The story will reveal the origin of the super-powered, lighter-than-air teenager.
 
Joshua Dysart (Harbinger, Unknown Soldier) will write, with art by Robert Gill (Armor Hunters: Harbinger) and main covers by Joe Quinones and Lucy Knisley, with a variant by Brian Level .  The 32-page one-shot has an MSRP of $3.99.
