This is a great resource, much better than the more popular DM Guide by Eventyr. It ties everything together, fixes all the plot holes and things that don't make sense in the module and really expands on the descriptions and has lots of great scenes that improve the narrative, I wish I had found this sooner, my campaign got much better since I started using it.

Extremely helpful guide to use in whole or part to make more sense of the WOTC module. This is one of the best-written modules, but still has a lot of glaring holes that the Companion fixes. Explains the narrative benefits of the changes it proposes, highlighting things that wouldn't necessarily occur to a new DM, and providing good material even for experienced DMs to use or jump off from.

Any WOTC product I buy, I'm checking on what Wyatt Trull has done to improve it.!
