5E Druid Subclass: Circle of the City

From publisher blurb:

Most druids find themselves drawn to the wilderness of nature, but that is not the case for all. Some instead seek the companionship of other people and join them within urban settlements. They find joy in the little things—helping a flower grow from between the cobblestones or treating a draft horse with a limp gait. These druids aren’t a common sight and their powers aren’t something they speak loudly about. Instead, they serve as silent guardians of their cities, quietly assisting where they are able.
