Ankou's Unsharpened Scythe

The Frameset can only be accessed through a Nascent Vent. A Nascent Vent can only be accessed with an Umbra. The Umbra can only be released from its Hull with a violent death. Few seek a violent death, but since Elliot was already considering death, he doesn't see any harm (he absolutely sees the harm) in making it a bi-bird murder stone and reclaiming a sixteen-year-old metabolism and some linebacker glory. Yes, yes, blood, sweat, and tears, and all that, but, as his eccentric, mustachioed grandad (who never wore an eye patch) would say, Value is sacrifice's dividends. All Elliot has to do is blindly outwit the timeless machinations of secret societies, learn the ways of the Pikirovateli, and smash himself into an Apical Frame at 71 miles per hour using only a density differential and a Mega-Helium Pocket Fly Suit.
