Free Adventure Friday: The Hand Behind The Fang

Most of my #freeadventurefriday posts have been from adventures I've already one. This week I gave myself the challenge of making the rough draft for a randomly-generated adventure in one hour. I think it went pretty well, so I'm planning on doing this process live on Twitch tomorrow at noon Central time at https://www.twitch.tv/important_fun

The Hand Behind The Fang is a free Dungeons & Dragons 5e adventure for level 7 characters in which they attempt to stop a tribe of gnolls from raiding a nearby village. But what is driving and organizing these gnolls? (Spoilers: it's a mind flayer)
