Oleander's Sanctuary (5E)

From publisher blurb:

Deep within a dense forest lies a well-hidden, secret path leading into the wood’s wildest and deepest recesses. The only sign of civilization for miles on end upon the winding path is a distant thin finger of smoke wafting up through the trees. All manner of animals lurk in the surrounds seemingly drawn to the little hut and surrounding buildings hidden deep in the forest. Here dwells the so-called witch Oleander, a mysterious being possessing incredible powers she uses to heal and improve animals seeking her care.
