So I encountered the 3D puzzle in BG3 (trying to avoid any spoilers) and fell in love with it's design and concept (even though the concept is far from new) and I'd absolutely love to introduce something resembling it into my DnD game (I use FoundryVTT for reference). Obviously, I know the 3rd dimension would be overly difficult, or not worth the effort even if it were actually possible, so I'm totally down for a 2D representation (which I have documented) but I'm curious as to how to actually implement that in a fun way.

My first thought was to have all "nodes" arranged in a circle with curved lines connecting the correct path (and others) where a player can move along the line from node A, where I have a small blue light, for instance, along to node B, where I change the color of its light to blue as well as the color of the line traversed.... Yeah, it's a little leg work for myself as the DM, but I regularly put in way too much time and effort into my games. lol

Another thought

TL;DR Cult of Dragon / Wizards of Thay have captured my level 19 party. Meant to have cult leader be the mastermind (which would have made plenty of sense) but "accidentally" had the leader of all of Thay be there instead. Looking for good story-hook to have him involved to keep from having to retcon half a session (and possible compelling storyline)

First off...... I sincerely and genuinely apologize for being wordy in the following....

Background for context: My 5 players are all level 19 (leveling to 20 next time the can take a break). They've gone through all of the official Rise of Tiamat material and have finished several months of homebrew stuff to get them from lvl 15 to 20, culminating with them gathering spell components for Blackstaff to protect Waterdeep. Some months back, the wizard had gotten disintegrated by the cult and the cult of the dragon had recovered his gear, notably including a Staff of Power, +2 Ring of Protection, Ring of Spell Storing, a bag of holding, Rin
