From website:
Since 2009 it's been my great pleasure to write Dungeons & Dragons articles for http://slyflourish.com every week and #dnd tips each day all to help DMs (myself included) get better at running great D&D games.
I've posted all of these articles, tools, and tips on Sly Flourish for free over the past decade and will continue to do so. Over the years I've paid for the expenses running the site from the sales of my D&D books including Return of the Lazy Dungeon Master, Fantastic Locations, and Fantastic Adventures.
