Glir's Guide to Ranging

Glir's Guide is a handbook for wilderness wanderers and trail guides, covering tracking techniques, plant and animal identification, and also a collection of lesser known spells useful to such work.
It appears to have been first published in The Karthin Cities, most likely Windcliff, some time in the 2600s AS.
Most copies feature vellum pages and leather binding, to increase survivability in rough conditions.
