Iron and Leaves
Rangers were once sacred warriors and shepherds and gardeners of the wood elves. The rise of orthodoxy has stripped them of much of their status and religious authority. Officially they are now soldiers and border guardians, as well as police. They keep the elven woods safe.
However, their earlier devotions and rites haven’t vanished, they’ve just become hidden from outsiders. The rangers are now a secret society within a military and police organization.
For now, they still keep all elves safe, but as tensions continue to rise between wood elves, high elves, and dark elves, some murmur that they should take care of their own (wood elves) first and foremost.
