The note unfolds as a profound, multifaceted olfactory journey into the heart of an ancient forest after a heavy rain, yet shadowed by an enduring darkness. It presents a robust, earthy aroma, immediately striking with its damp soil nuances, wet moss underfoot, and the distinct, almost feral scent of decaying leaves and rich humus. There's a deep, leathery woodsiness that isn't merely dry or sawdust-like, but imbued with a resinous sap and the aged character of dark, gnarled tree trunks. Hints of smoky char and mineralic dampness weave through its core, suggesting the faint embers of a distant, forgotten fire or the cool, stony presence within the forest's depths. Its texture is rugged, almost tactile, evoking rough bark and moist earth. Initially, it projects with a quiet intensity, a deep hum rather than a sharp burst, settling quickly into a long, lingering base note. It is exceptionally tenacious, forming the very backbone of a composition, evolving slowly from its initial damp earthiness to a drier, more profound woody-amber character over many hours, often revealing subtle nuances of balsamic sweetness or a faint, clean petrichor as it dries down. It rarely acts as a top or heart note, reserving its grand entrance for the foundation.
