Echoes from the Other Vault

The party stumbles into a small, sealed cache tucked beneath an old surveyor's beacon at the edge of an unmapped moor. There was no trapper or guardian left — only faint residue of planar whispering and an arrangement of objects laid as if by careful hands from somewhere not entirely like this world. The haul reads like the inventory of a scholarly explorer who trafficked in strange horizons: a handful of useful crafting components for planar or arcane work, a couple of portable curios for navigation and ritual, several gemstones and art objects to fund further travel, and a single tempered blade that carries a faint, impatient hum. No monsters were involved; this is the sort of find a level 7 party might excavate from an overlooked waystation or barter-house frequented by planar cartographers and other wanderers of the 'Other'.
