This is a collection of 8 one page adventures using 8 different basic planes. These adventures are intended for levels 11-15 and take 2-4 hours to complete depending on play speed. The intent is to provide easy to insert content into an existing campaign while traveling. The included planes are Earth, Air, Fire, Water, Dawn (fae), Dusk (death), Order, and Chaos.
I am currently working on a new collection of adventures for the 11 different environment types for levels 11-15 which you can see on my patreon page as its being worked on. When its done I will be releasing it for free here.
