Then the more I got into mapping Oerth the more interested I got  and starting to see possibilities and overlooked connections with the familiar stories of our favorite game […]

Hot Oerth

Previously we looked at the "normal" Oerth and then a Cold Oerth gripped by an ice age, now its time to look at the opposite Oerth scorched by a scorched climate a bit more than ten degrees above normal. This model is a bit more speculative than the normal or cold, science on ice ages […]

Cold Oerth

This one turned out to take much longer than I thought, I got caught up in its intricacies realizing its historic potentials. My premise for this version of Oerth is a version of Oerth not too long ago, geologically that is. How long ago is up to you in your campaign, but recent enough for […]
