I was waiting for this exactly. I even thought about getting into modding. Merci beaucoup!

Pardon my NOT French - I'm sure nobody would want to read my French. xD

Some feedback …
I do not know anything about making workshop mods and scripting, so don't take me too serious.

I still get the "WWW Image Error: Cannot connect to destination host" like @Argone, so the reupload from 3.5.'20 seems not to have worked.
The standees of the gods, enemies and foes do not load. I only see empty stands (all of them are round. If you want to stay true to the original you could make rectangular stands for the gods) and little white placeholders were the objects should load, but cannot.

It looks like you scanned the rulebook. This was not necessary as you can download the PDFs in all three languages from here: https://www.ludonaute.fr/ydc-telechargements-downloads/
You could also put the English and German rule and scenario books into a bag. The components are so greatly language independent - we should make use of that.

I think it would be better to have the scenario book double-sided (displaying the even and odd numbered pages next to each other at one time), like this:

(Sorry, Ludonaute only published the German version digitally so far.)

Please, if you like, you could add my player aid for artifacts and creatures. I have them in English and German now. Would you like to help me make the French version, FloBEAUG?
You can find the files here, among other things:

Loki doesn't start out in Vanaheim ᛈ where he should be for me (at least there is no stand there, but there is one in Iotunheim ᛁ).

It would be AWESOME if you could add snap points to which figures can snap.
The paths to the sun and moon for Skøll and Hati, the islands for Iormungandr, the slots around the cage for the cage walls, the positions on the strength ladders of Loki, Hel, and Surt; the positions on the sword of obstacles for Iotun.

The strength ladder of Surt is a little too low. You should lift the whole component or the texture of it a bit if possible.

Would it be possible to put the instructions for the scripts somewhere else and/or add other language versions?

[UPDATE for next paragraph: It works now, I don't know why it didn't work before.]
The script for adding pawns to a strength ladder doesn't work for me, but maybe that is because I do not know where to point the mouse. I tried all places that made intuitive sense to me, but I always got an error "Error in Script (Global) function <onScriptButtonDown>: chunk_3:(34,4-56): attempt to index a nil value"
Also, not every keyboard has a numpad (many notebooks). A script button in an edge of the table would be a great addition, for turning the tree and also for adding and removing pawns to and from strength ladders.
UPDATE: I see why you are using numpad. It's the default for index. I didn't know this before, sorry.

The script for turning the tree is awesome and you are a genius! I love it.
Maybe you could deactivate the hotkey while the tree is turning, because when you press 2 again (I know, you shouldn't, but if) it will turn the tree again by 120° from that position.

Maybe you could add another script for returning the "devastated world" markers to the cage wall. I naively would think that it could be similar to the script with index 1.

You could even add it als a branch of your onScriptingButtonDown(index, color) function like
if ( index == 1 and obj.getName() == 'MarqueurMondeRavagé' ) then
replaceMarqMR(obj)
end
or something like that. I do realize that you probably can't use the same functions you wrote for the pawn, because the markers are not joined together around the cage, so you cannot "count" how many are there at the moment … but you are the genius, so I guess you'll figure something out.
Putting them back manually is possible but again, a bit fiddly.

You could add a bag for the oath/promise tokens, so they can be shuffled without looking at them. When put them in face down and shuffle the bag, they will come out still face down, but in a random order: NICE!
You could spawn the tokens inside the bag and have an initial shuffle on the bag as you have for the three types of cards (artifacts, creatures, Iotun).

This game could make use of lots of scripting, but I myself don't know how to do any of it.
Still, what you achieved is really wonderful as it is. If you can fix the loading of the standees / figurines it would be well playable.

I sent you a friend request, because you are a hero to me!
