Eadmund has learned... some of the ways of Ninuan.* He is, after all, royalty of the Host. It would be embarrassing for him to get turned around every time he stepped through a Waylet. But he doesn't have enough Lore in his skull yet to navigate the deep roads, out beyond the snowy countryside into the eddies and whirlpools of nothingness. So it's rather inconvenient when, while he's navigating a rather treacherous path that could be said to have some acausal "aboveness" in relation to a particularly nasty patch of void, something slams into him and sends him tumbling into the black.
A mortal would be unmade. Well, a mortal couldn't have gotten that deep into Ninuan in the first place without being unmade - but a Power, say, some jumped-up mortal with total command of bees or salt or truancy, would be unmade. Eadmund, though, is an Excrucian. Eadmund is a Strategist. Eadmund is royalty, of a place that never existed but did so long before any upstart empire of the World Ash.
So he just screams a lot, rather more high-pitched than he might care to admit, until he slams into some unreasonably real earth.
He picks himself off the ground and tries futilely to dust himself off, before remembering that he's a Strategist and just making it cease to exist.** Then he looks around. What misbegotten corner of the Ash has he somehow ended up in?
*If you were reading it right, it'd have the fancy N. It's not Eadmund's fault λ-letters aren't Unicode-compliant. The Consortium should have more space for infinite nonexistent alphabets.
**Not with the World-Breaker's Hand. That'd be overkill. He just replaces his raiment with the exact same thing, but without the dust. Where does it go? Don't worry about it!
