herkles a écrit :1.) What would their temples look like particular in the cities? I know that in more rural areas their would be groves with menhirs, but what of the various cities?
There is no "by the book" answer in that regard, so you're free to improvise however you deem it fit, but my stance on the subject is that urban areas must have spaces left as pristine as possible in order for the local Demorthèn to gather and meditate there. It also stands to reason that towns must have local monuments (menhirs, dolmens, shrines, etc.) dedicated to the spirits of nature.
2.) Do any of the spirits that are worshiped have names? for instance perhaps a local or major river is associated with a particular river spirit/goddess? would he/she have a name according to the Dremothren.
In addition to the answer provided by Iris, I also advise you to read the chapter about Demorthèn in Book 1 (p.140), particularly the box on p.142. This should be what you are looking for!
If you need other names, it will up to you to invent them
3.) relating to question 2; are their any spirits that are worshiped as gods, or just worshiped more often then others due to how they are associated?
The four primordial spirits (Adhar, Usgardh, Roimh, and Aingeal) are the four major deities of the Demorthèn, so Demorthèn rituals must involve them frequently, whether to ask for their blessings or to placate their wrath.
Luohu a écrit :In fact, are there any shrines or places of worship for Demorthèn in big cities (such as Osta-baille, for example)? Or are they all situated at the outskirts of cities, in areas of wilderness?
The first part of my post partly covers this question.
Places of worship located inside a city would probably be a sign of consensual Demorthèn influence, whereas having them remain separate from the town itself would be a clear manifestation of distance (both physical and ideological), or even of hostility with the local power.
However, it seems important to me to stress once more that there is nothing set in stone on the subject at the time, and that you are therefore free to do as you see fit. Do what you and your Players are most comfortable with!
Now about spirits: Do they all embody elements of the natural world or could Demorthèn worship urban-themed spirits (such as a spirit reprensenting a particular street or road, a spirit reprensenting a building, a spirit of the sewers, etc.).
By essence, the spirits are spirits of
nature. The idea of "urban spirit" would be completely absurd to the mind of a Demorthèn. To them, it would be like suggesting that a bee could pollinate stone!
