I see the Drykas as not only based off of Native Americans as many have suggested, but also the Drykas have a lot of Celtic intertwined with them. They are neither this or that when it comes to finding an exact definition. They are not tribes people, they are not exactly Native Americans, they are not exactly Celtic, they are a mixture of all things and created with many things to make them unique. I could be wrong about this but from what I have read so far, there is many implements from different cultures that we see in RL that forms the Drykas.
With that in mind I do not think focusing only on one modern day example would be quite right for Drykas. But perhaps as a basis it would be okay, expanded upon and created into something that fits in with the unique culture and peoples of Endrykas.
I love the dance idea and feel like dances should be a way to honor different things that happen among the clans. Marriage, birth, death, ect. Death should not be a mourning but a celebration as they return to the web that surrounds Drykas and they are still near and could be reborn as a Strider as the lore mentions. Perhaps the dance tells the story of those who die returning to the web, to be reborn once more as a Strider who runs free? I also feel like when it comes to dancing, horses could be incorporated as well. I know it sounds silly, dancing with horses, but skilled riders and acrobats could make this possible. It would be something similar to the girls who perform on horse back at rodeos, but not like that. Instead it would be a more cultural, spiritual dance, made between the rider and his/her strider, to perform a dance of the bonded. Just an idea

. I think dance is not just the human body, but with horses being a major part of Drykas, dancing with your horse could be interesting to see.
I think the music they would have would be something that is easily traveled with. Drums, flutes, ect. Something small and travel ready. That is not to say the focus of the music should be Native American, but I see the music style being something that is Native American and Celtic both. Something spiritual yet freeing, a type of music that calms the animals and the souls of those who hear it. During a celebration, it could be a type of music that makes the body sway on its own, hypnotizing in a way. That is what I see, as they have down time when the sun begins to set, there could very well be many expert musicians who played the flute to lull their little ones to sleep, to calm their wild strider, ect.
As for the Grass, Caesi has done a couple of threads using the grass that surrounds Endrykas to weave baskets. Someone with a higher experience in Weaving could use the grass to make other useful things that the Drykas need daily. Like how we today make hemp rope, they would make a grass rope in the same way. Grasses could be used to make wine as suggested, bindings, blankets, mats, something to sleep on, whips, leashes, ect. The grass could be dried to turn into a stark brown, dyed with berries to provide color and used to adorn things. There is so many different ways you could use grasses. Like weaving the dried grass into a basket instead of the green grass, you could use berries to dye the baskets to make them more colorful and matching the Clan you hail from. The grass should definitely be integrated more, as the people of Endrykas use what ever they can at their disposal to live, survive and prosper. The Grass Wine I feel would be amazing, it could be a wine only found in Endrykas and sold at a high price to foreigners or traded at a high price, as the brewing of it should be kept a secret to that particular clan or the Drykas people.
As for the religion aspect.. I think it is very important as well. Perhaps there should be link-map locations of ruins of old, where their ancestors worshiped this god or this goddess. Instead of a shrine you carry, shrines that have been there for many years and is integrated into the very foundation of the Drykas Culture. Ruins of Shrines that have survived over the years, that they go to at specific dates to worship that God or Goddess. Since they are at different locations due to them traveling, one or two shrines should be in place at different locations.
In the Spring it could be Caiyha at that location, in the summer it could be Zulrav at that location. Ect.. Ect.. Once they are at that location, all who can gather at the shrine to pay homage and respect to that particular deity. It could be like a festival of such but more of a culture thing and it would provide an open thread for all players to come and pay homage to their god/goddess and perhaps later on this could be where a god/goddess interacts with the players to either bless them, curse them, appear with a message, a quest, a test, ect. This would provide plots for that season given specifically by that deity. It could be fun

. I would like to see other Deitys as I usually only see Zulrav, Caiyha, and Semele thus far. Perhaps a few more should also be paid homage, like Aquiras as mentioned previously. But there is also Eywaat, Kihala, Makutsi, Xhyvas.. If music is going to be a big thing maybe even Rhaus. Not saying all of those, just giving examples of the deity's that seem to fit in with the Drykas and who are rarely, if ever, used by PCs.
Magic should be revered and feared. Certain magics should defintely be feared by the people of Endrykas. While others should be revered.
Examples:
Leeching is where you absorb magic from others, this should be feared as it would sap the magic needed to keep the Web in place.
Familiary should be revered as it is somewhat animal base...right?
Reimancy should be revered as it deals with the elements found in nature, yes even Earth, since those marked by Semele has the ability to harness the power of rocks and gemstones, not sure why manipulating earth would be feared and creating a fireball would not be? But that is my own opinion

.
Summoning is dangerous as they could bring in monsters that do not do their bidding and ultimately destroy a whole clan or Pavilion.
Perhaps a list of what is accepted on magics and what is not would be too specific and would not let Players take their PC where they would like to? Then again, perhaps it should be implemented as it could keep people coming in and destroying a Pavilion with their evil magiceseses ... haha. Just my opinion and adding my own two cents on the matters here.
