"One? Are you sure?" —Prophet of Regret
"Yes. They called it the Pillar of Autumn." —Thel 'Vadamee

The UNSC Pillar of Autumn was a Halcyon-class cruiser, and now it’s a prop for your Xbox 360 Avatar, too! So, whether you have a thing for large ships or for sassy, artificially intelligent characters, check out the newest additions to the Halo Avatar Collection: a Pillar of Autumn Avatar Item and a Cortana costume. They're available now on Xbox LIVE.
