"A grove of aspens stands above the surrounding forest, blessed by a fey magic with leaves of blue, violet and orange among the vivid green. Two mounds stir at your approach, rising from two low pits. These mounds of shrubs and foliage have several silver and bronze icon attached to them"

Are these guardians or masters of the grove? who put the icons there?

Forest Encounters

Forest can cover pine uplands, sylvan forests or thick jungle canopies. Encounters might take place by a giant fallen oak, in a sylvan meadow of mushrooms or among overgrown standing stones.

The woodlands are full of life, with greenery and beasts at every step. It is home to feral druids, cavorting fey, beast hunters and primordial creatures best left alone.

There is a 5e forest random encounter generator at ChaosGen. And also a pdf of these and more tables at the DM's Guild as Forest Encounters.
