I'll explain how your values effect your government and economy in more detail later.
In general, the values of the Arthwyd leave them unified and loyal to each other and the overall community. People treat other respectfully and well and there is plenty of personal freedoms (for the tech level). The People are happy with their goddesses and the priests. Furthermore, in times of crisis and war, the Arthwyd will rally around each other as they will stand by their community against outside threats. For the players, it means that you are obligated to look after your people even if it isn't cost-effective, it isn't the pragmatic choice or you would rather expend resources on something else. This can be either being forced to fight against an enemy until your people feel that they are no longer a threat to their community or it could being forced to infrastructure and benefits that the people feel that they are rightfully owed from their leaders.
It is a two-sided sword as while you are a lot more resistant to internal discontent and can put up a united front against outside threats, but your people also have obligations and expectations that you will need to met unless wish to suffer negative consequences going all the way up to the collapse of the civ as the people reject their abusive/neglectful leaders.
For now, you only have shrines and trails as infrastructure and since you have mostly keep up with them, but in future, people will be expecting things like walls to keep them safe, libraries for knowledge and learning, temples for spiritual needs, aqueducts and sewers for health and sanitation. You will need to provide them and make sure to stay on top of building enough, something that a Rush Builders Legacy would help a lot with (and vital for non-glacial expansion in the future).
The Arthwyd are a build tall civ and if that is to change, than Arthwyd civilisation must broken first so it may be forged into something new.
As for war, you really ought to avoid it unless you are going to fully commit to the long haul. This is because Loyal Neighbours and Communal Mandate force you to look after your people and aid them in times of need. As some people pointed out in the thread, the Arthwyd aren't going to cut their losses when the going gets tough as long as they got people to protect, save or avenge, they are going to keep fighting. This is particularly bad if the enemy enslaves some of your people, the Arthwyd are going to keep fighting until they get them back or avenge their loss and that could lead to some unending wars.
Furthermore, this means that you have to defend every settlement and is one of the reasons I classify the Arthwyd as a 'build tall' civ. You can't have border settlements that you can afford to sacrifice. You have to fight and keep fighting. You pretty much have to commit fully to a war and keep fighting until the bitter end unless you want Stability and Legitimacy loss from Communal Mandate and Loyal Neighbours respectively. So when it comes to war, you better hope it is one that doesn't hurt you or is a swift victory for you as otherwise you are going to be forced into endless war unless you can force the other side to make (unreasonable from an outside perspective) amends.
All in all, you will need to explain slowly as you will both have to build up your settlements with local infrastructure and make sure they are properly protected. So while this will end up limited your rate of expansion, it will also leave you with a well-off and highly developed core territory.
