Second Black Dawn is a fantastic alternative to long-form beginner adventures like Lost Mine Of Phandelver, Waterdeep: Dragonheist, and even my beloved Dragon Of Icespire Peak! Not only does this module ride classic D&D themes, but it also includes a section of DM advice complete with music suggestions!
This darker, more mature module includes recommendations for adding it to the Forgotten Realms, and it can easily be adapted to your own homebrew setting. The Black Hand, an evil cult of Bane, has allied with necromancers, goblins, and a royal traitor to complete a fiend-summoning ritual. There's even a zombie dragon! It's hard to get more D&D than this module.
The layout is professional, and while the art and maps range in quality, the quantity is impressive. Likewise, my only critique is that the heavily descriptive nature of the story will require a lot of DM homework, but it will be worth it!
[4 of 5 Stars!]
