This set of five identical compasses are lacking the distinctive cardinal direction markers you might be expecting, and you also note they each have four pointers, rather than one.

This item is a rodent skull, weathered from years of exposure to the elements, with it’s mouth wired shut around a vial of water. Inside the vial you can see a pink lily bud floating on the surface. This bud always points towards the closest natural water source, no matter how far it is. If there is no natural water source on your plane of existence, the lilly will wilt and remain wilted until it returns to a plane with water.
This tiny crystal sphere features an intensely detailed mountain covered in loose snow. When you shake it the snow flies around the miniature landscape, creating a swirling snowstorm. The wind in this diorama always blows towards the point of highest elevation in your current plane of existence.
This small ornamental arrow is the length of a man’s hand and has a shard of dragon scale for it’s head.
