Pretty active, though it really just depends on how active you want, or are able to be.
Of course, the more active you are, the more rewards you get.
We have new events every month and constant story progression, but participation is always optional.
We post story conclusions for people that maybe didn't have the time, but would still like to be up to date on what has been happening.
We have non-DA Members too, so using DA is not a requirement.
Most of the action and announcements happen in our open Discord.
