There is no letter equivalent for Gar
There is no rune poem for Gar. It is a Northumbrian Rune.
My sense about the rune of this week is that I need to take a break for this week from doing my regular rune posts. Let things clear out, and come back next week. Of course, with my class beginning this Wednesday, June 16 at Points of Light, well that might also be a good time to just relax and let myself focus on being thoroughly prepared.
