Koshirone Tree, Aokure no Ki | 青暮の木
Basic Information
Anatomy
The Koshirone Tree stands between 18 to 24 meters tall at maturity, with a thick, spiraled trunk of pale gray wood that carries a faint internal glow beneath its bark—an effect that intensifies at night. The bark itself splits in irregular patterns resembling calligraphy strokes. The branches are layered in upward spirals, giving the canopy a lantern-like silhouette when seen against the night sky. Instead of leaves, it bears fine, needle-like fronds that shift between soft teal and deep blue depending on the season. The root system is wide and shallow, often sprawling into and over rocky surfaces, anchoring the tree even in high winds.
Biological Traits
There are no distinct subspecies, but some ancient Verian scrolls describe “Sapphireheart” Koshirone, a rare mutation that exhibits vivid inner bark markings and may produce music-like tones in the wind. Males and females are not differentiated; each tree produces its own glowpods.
Individual trees live between 500–800 years, with some groves believed to contain elders over a millennium old, though these claims remain unverified due to the cultural taboo against cutting core samples.
Genetics and Reproduction
Koshirone Trees reproduce via glowpods, pale-blue seed cones that emerge once every 18 years. These glowpods fall and bury themselves just beneath the frost line, remaining dormant for up to five years before sprouting under specific temperature and leyline conditions. Germination requires both snowmelt and exposure to moonlight over a full seasonal cycle.
Growth Rate & Stages
Young saplings grow slowly—about one meter every three years—and take approximately 120 years to reach full maturity. The trees live for up to 800 years, gradually growing more gnarled and luminous with age. As they mature, the spiral of their branches becomes more pronounced, and in rare cases, ancient trees exhibit a full helix canopy.
Ecology and Habitats
These trees thrive in cold alpine altitudes, typically between 2000–3000 meters above sea level. They grow best in thin, rocky soil with high mineral content, often sprouting in windswept gullies or narrow terraces between cliff faces. Their roots anchor into stone more than soil, drawing nutrients from trace mineral deposits and snowmelt runoff. Koshirone groves tend to form in crescent arcs, responding subconsciously to the flow of ley-energies beneath the mountain.
Their presence stabilizes erosion, supports moss and lichen colonies on their bark, and offers shelter to cliff-dwelling birds and insects adapted to cold highlands.
Dietary Needs and Habits
As a photosynthetic species, the Koshirone Tree absorbs light, moisture, and trace nutrients. What makes it unique is its subterranean root lace, a fine network of hair-thin roots that extract metallic essence from rock and glacial water, which contributes to the wood’s density and slow-burning nature. It stores moisture in resin knots located near its base, allowing it to survive prolonged dry winters.
Biological Cycle
In spring and summer, the needles shimmer with blue-green iridescence and release a sharp, cooling scent when brushed. In autumn, the fronds turn deep indigo, and the tree’s bark pulses gently during sunset—an effect believed to coincide with a draw in divine resonance. During winter, the tree appears dormant, though its internal glow becomes brightest under snowfall, giving it an ethereal quality often compared to lanterns guiding lost spirits.
Behaviour
The tree does not move or react rapidly, but it has long been observed to subtly adjust its canopy alignment toward magical disturbances and lunar movement. Koshirone groves do not compete for space—older trees appear to nurture younger saplings through shared root-laced networks, which transmit nutrients and possibly arcane resonance. The trees show no aggression but appear to “retreat” from corrupted land or sites of recent arcane catastrophe.
Additional Information
Social Structure
Though not a social species, the Koshirone Tree is believed to form ancestral networks when growing in small groves. Some Verian philosophies suggest that groves are the “echoes” of ancestor spirits given form. Monks often meditate among them, claiming the trees help align one’s inner voice with memory. Yogul druids refer to them as “the Vein-Bearing Roots,” believing they grow along buried veins of the world's memory.
Domestication
Koshirone Trees have never been domesticated, nor have efforts to transplant them below their natural altitude succeeded. However, their deadfall wood is considered sacred and is used in the crafting of prayer staffs, shrine arches, and musical instruments. The resin is sometimes collected for incense and lantern oils by Verian monks, who consider it a gift of guidance.
Uses, Products & Exploitation
While never harvested directly, the tree’s fallen branches and resin are widely used in Verian sacred architecture, religious rites, and in the creation of meditative music instruments. Powdered bark is a key ingredient in certain dream-teas, believed to ease the soul during prophetic rituals. Yogul practitioners have been known to carve masks from its wood, though these are rare and often part of multi-generational totems.
Geographic Origin and Distribution
Primarily found in southern Veria, along the higher elevations of the Varran’del Ridge, with a few solitary trees appearing at the northernmost edges of Yogul’s elevated forests. The species does not naturally grow elsewhere.
Perception and Sensory Capabilities
While not sentient, the Koshirone Tree possesses a unique magical resonance. It is sensitive to changes in leyline pressure and to divine spellcasting. Some Verian monks believe that the tree “sings” faintly in the presence of divine energy, and musical instruments made from fallen Koshirone wood are prized for their ability to hold subtle harmonics. The tree’s bark is also slightly reactive to lunar light, especially from Velas, and glows faintly under its full presence.
