For transparency, I won my copy of this adventure in a Twitter giveaway.
This is a beautifully crafted and formated adventure of the higher end of production quality for DMs Guild with wonderful original cover and interior art by Alexandros Balatsouras, including a detailed dungeon map, as well as artwork for original creatures, magic items and NPCs.
It is clear from the extensive plot hooks and their relation to various factions, substantial lore for the Crimson Order, the NPCs and a thorough overview and rundown of the adventure this is well thought out and crated with passion. This lore and grounding the cult and its officers, as well as elements of the adventure lay the groundwork for further adventures and coild easily be the base for a full campaign. This is handy as the adventure does potentially end on a cliffhanger, but with the establishing details, being left wanting more only serves to drive and inspire further adventures. I look forward to further adventures from this design team, their characters and Forgotten Realms (or any really) compatible world.
The core of the adventure is rescuing kidnapped magic users, exploring the Crimson Order's Lair and the eponymous laboratory and facing new and rather horrific undead minions created within, before a final confrontation and an open-ended ending with suggestions of what to do next. Essentially it's a decent sized single floor dungeon crawl filled with fabulous flavour. Relatively short (depending on how your party approaches this sort of thing), but certainly sweet.
The appendices are extensive, containing five original thematic and powerful magic items, four original bloody undead creatures, five NPCs all with their own full statblocks, and two unique cultist variants. These are accompanied and complimented by seven quality illustrations, with the magic items depictions particularly standing out.
This is a great adventure at an extremely low price for the quality of the content. I would certainly recommend it and feel inspired to incorporate the adventure, Nameia and the Crimson Order into my game, as well thoroughly looking forward to the upcoming release of Nameia's Crimson Tome.
