Circle of the warden

Every druid has a responsibility to the natural world, but
those who join the Circle of the Warden stand as sentinels of
nature’s balance. The Circle of the Warden specializes in divination
and abjuration magics to help foresee possible imbalances
and correct them before they cause irreparable damage.
To druids of this circle, people are as much a part of the natural
balance as plants and animals. As such, these druids can be
found providing succor to those affected by natural disasters
just as often as to the flora and fauna. In Humblewood, many
druids who have joined the Tenders of the Scorched Grove are
members of this circle, as its values align quite closely with the
tenets of their order.
Heartbeat of the Land
Starting when you choose this circle at 2nd level, you form
a connection to the natural world around you, and you can
sense when it is in danger. You gain proficiency in the Nature
and Insight skills. Your proficiency bonus is doubled for any
ability check you make that uses either of those proficiencies.
Additionally, by spending 10 minutes communing with
nature, you can glean the following information about the area
within 3 miles of you:
l You learn the general location and severity of any immediate
threats to the environment in the region (forest fires,
flooding, blights, etc.).
l You learn if any aberrations, beasts, elementals, fey, or
undead are present within range, but not their specific
locations.
l You learn the general direction of the nearest portal to an
elemental plane.
