Shakespere and Dragons is a long ended but incredibly useful podcast from 2007. Paul Stark who published 15 episodes is an english teacher with a love for scifi/fantasy and dungeons and dragons and put together this series which is a really practical set of tools for building tone, theme and for worldbuilding a setting and then integrating characters into that. Its incredibly sad that the podcast ended but seems like Paul couldnt find a balance between his own writing and the podcast and so had to give it up. This podcast helped me jump out of "what do I write" into a simple set of steps for building a series of characters and fleshing out that "vibe for a setting" in my head into an actual concept for my story.
Write about Dragons is Brandon Sandersons website. He wrote the Mistborn series and most famously completed Robert Jordans Wheel of Time series. He's a fantastic teacher and his entire semester of lectures from 2013 is available for free download from his website. Its a great resource for all sorts of basic lessons for the aspiring writer, both writing (perspective, character development, plot construction) and the professional tools of the trade (getting an agent, publishing, contracts etc). Exploring the website outside the lecture content is also totally worthwhile.
is a Podcast Brandon sanderson has been a part of as well for a long time. Theres 9 seasons made up for a few writers and a web comic artist talking through all sorts of topics relating to writing. It jumps around but there is a ton of excellent content in there!
