Okay, Hell-riding to an item takes a day per point; this can easily become weeks or even months. If you're in no hurry, rather than rush, you could travel the Royal Way - slower than normal Shadow Walking much less Hell-riding, but then, what were you planning to do with immortality anyway?
The Canterbury Route is a pilgrimage route across similar Shadows - the Amberite travels with a group of pilgrims enjoying their Holydays, riding slowly across the landscape, telling tales and recounting adventures. The Shadows are similar enough that the Shadow dwellers who accompany the Amberite don't realise what is happening, and may end up going 'home' to the wrong Shadow without being any the wiser. Fortunately, the mounts on the route are (mostly) imbued with the Follow Shadow Trail ability, and can get most of the pilgrims home.
Being sought by travellers who desire company, several Shadows on the Route are Destined to have Amberites or other travellers meet when they are in the mood to talk - their paths will then diverge again when the urge to talk had passed.
Generally, the item desired is a sacred relic held at the site of the pilgrimage, so replacing it would be polite. (Possibly an Amberite at some point has conisdered this, but I'm not holding my breath). For some unknown reason, while travelling the Canterbury Route, pilgrims will often hear rumours of sacrileges thefts, that are denied/unknown a few days/Shadows later.
As the name indicates, the primary purpose of the Canterbury Route is entertainment, and a chance to spend months listening to (or spinning) tall tales with holidaying friends.
