There's some satisfying synchronicity here, as the printed World Tree booklet has started to arrive with patrons, and the matching PDF is now available on the darkest day of the year!
Cover art by Justine Jones, and interior sections by Wolfgang Baur, Kelly Pawlik, Richard Green, and Sarah Madsen on many topics related to the Northlands and the planes, especially the Tree Whose Branches Cross the Worlds.
You can grab your copy from the Kobold Press store with code Sol5tic3 until March 31, 2019 (That's somewhere around the equinox).
Happy holidays to you all, and a joyous New Year!
