Ythryn Expanded Tower of Necromancy - maps and extra content for Rime of the Frostmaiden



The Tower of Necromancy was one of eight towers of magic in the ancient floating Netherese city of Ythryn. Now the tower, along with the city, lies trapped in a frozen tomb. The wizards of this great tower are either long dead or have lost their minds to madness. Yet the tower still holds powerful magic waiting to be tapped.

This supplement is one of several short expansions to the locations in Ythryn with the following objectives:

  • Expand on the Eight Arcane Towers, making each one its own mini-dungeon adventure with exciting challenges and clear direction for the DM.
  • Provide Detailed Maps, for an immersive experience in person or on a virtual tabletop, rather than a brief 'theatre-of-mind' scene.

This supplement presents the events that occur in the Tower of Necromancy as an alternate to those described on page 246–247 of Icewind Dale: Rime of the Frostmaiden. Additionally, the process for the Ritual of Brain Transfer described within differs from what is described on page 249 of the bookAs always, it is up to you how much of the content you want to use. It's perfectly fine to use some parts of this supplement while discarding others, or simply let the ideas presented here inspire new ideas of your own. This supplement assumes a party of 4–6 characters of 9–11th level.

Adventure Summary: 

After their arrival at the Tower of Necromancy, characters will meet a brain in a jar who is trying to learn how to extract the brains of others. The brain suffers from delusions that it is still human and that everything is mostly normal. The characters can befriend the brain by helping it, or potentially cause it to become violent if they draw too much attention to its true reality. After dealing with the brain in the jar, the characters can proceed up to the top of the tower where they find the remains of High Necromancer Cadavix, who has been trapped in a magic jar spell of his own design since the Ythryn fell. Cadavix knows the Rite of the Arcane Octad, but needs the party's help before he gives it to them. Cadavix attempts to use the magic jar spell to possess the body of one of the party members in order to bring his own body back to life and discover the fate of his lover.

Looking forward to running this for my players who've just made it to Ythryn. Just a heads up but Handout A for the Necromancer Tower is actually the same Handout A for the Tower of Illusion.

Thanks for letting me know Eric. I just re-uploaded the handouts for both Necromancy and Illusion just to make sure they're right now. You should be able to download the updated handouts from your Library. Please let me know if there's anything else. :-)

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
