This week, I am sending my players into a metaplane in search of someone whose spirit was "lost" there. As this will be my first time doing anything at all with metaplanes, I would like to gather some input from people who have used them in their stories.
The team is getting to the metaplanes by way of a rift that a more powerful theurge is "holding open" for them. The metaplane will be the metaplane central to Shamanic tradition (focusing largely on Earth and Beast), and will use a sort of woodland metaphor. I plan on having the team come across a town of "animal people". Just outside of town will live a "tinkerer" - a human mage on a metaplanar quest of his own, who will come into play later in the story.
So, with all that in mind, what suggestions do you guys have for describing the metaplane? Should I play up its strangeness, or act like it's just a forest? Beyond the description in Street Magic, are there any sourcebooks that detail the metaplanes?
