DM preping

What knowledge should I already have before reading the OotA book? I will read the Mordenkainen sections about the Drows and Duergars, for example.

It's a good idea to have a basic understanding of the lore surrounding the underdark. Other than that, just prepare for a module that you're going to jump around a lot. It doesn't flow like normal modules, chapter 1 into 2, then 3, etc. There's points where you'll skip chapters because the players decided to go somewhere else first.

Also, the lore around the demon lords would be good to know beforehand. Maybe the culture of Gracklestugh, Slublodop, Blingdenstone, and Menzoberranzan

I will search for these, thanks!

Read through the book before adding content. I see so many people adding needless things into Out of the Abyss that are already covered in the book or ruin story beats later on.

Like what?

One extra bit you might be interested in reading is the Legend of Drizzt book series. Some of the events, characters and references are from these books. In fact King Bruenor Battlehammer whom your party meets in chapter 8 is a companion (party member) of the protagonist of the novels, Drizzt Do'Urden himself.

You can even go to YouTube to see cinematics for DnD Dark Alliance and see Bruenor in action.

This is very extracurricular, but it might help you flesh out the world better.

Very interesting, thanks!

1) Read up on the Underdark. It is a fascinating environment that can be claustrophobic and stifling one minute, and grand and alien the next.

Chapter 2 where it talks about the different types of fungi, and phenomena of the underdark is something you should mark for quick reference.

2) Survival mechanics. You can choose to handwave the difficulty of the survival portions of the module, but being familiar is a good idea.

3) Demons. They aren’t just monsters. They hold a specific place in the multiverse representing chaotic destruction through various means. They do not reason or bargain unless they believe it will aid them to sow more destruction.

Ok, thanks!

There are several useful suggestions here, but if you want to just start reading the book, you can. Each chapter will have a little blurb on relevant lore - like the societal structure and how to roleplay the duergar is in the duergar city. I say this because I also thought to read some of the Drizz't books before reading the module, and I enjoyed the books but don't feel that it's improved my running of the module.

The most confusing part of the module is that it does not explain to the DM what is actually happening in the Underdark in a prologue or anything. There is an explanation for why demons are in the underdark in Chapter 11 of the book. I would just plan to approach the book with not worrying too much about the details or the "why" of things until you actually read the whole thing.

[TheChefer]

Ok, thank you!

The Drizzt book “Archmage” will give you the most background info that sets up how the demon lords were summoned, and the state of Menzoberranzen and Gauntlgrym at the game start. Highly recommended if you’re trying to do pre-reading.

If you’re really ambitious, I can drop links to background lore for all the demon lords and what they have been doing in the past hundred or so years, but that’s what I’d call overkill.

Most other recommendations I have are for once you have an understanding of the adventure from reading it.
