First off is a Tweet from the 28th of December about a Moon Hills sheet:
He attached a screenshot of his Moon Hills Exploration but not the entire document.Mike Mearls on Twitter wrote:I talked a few days back about changing up outdoor exploration, here’s my first stab at it. Quick draft, concept is that the key is to make regions more interesting. Here’s reference sheet for the Moon Hills for my Nentir Vale campaign.
Then there was another Tweet about half an hour ago about a Witchlight Fens sheet:
There was a Witchlight Fens Exploration screenshot attached to that post.Mike Mearls on Twitter wrote:Follow-up to the outdoor exploration example from last night. Another region of the Nentir Vale, this one much more dangerous. Alterations I’ve made to the Vale poke through a bit more here. And yes, have noticed the disclaimer. Word uses my work template by default.
I wonder if he will ever release the entire documents.
