Berinu Rainwood (Aquabark ulmus)

Alias: Aquarex Elm
Origin: Berinu/Coastal Thazvaar (woodlands, marshes)

The Berinu Rainwood, also known as the Aquarex Elm, is a tall, resilient tree native to the fertile woodlands and marshes of Berinu and the coastal regions of Thazvaar. Its smooth, pale bark beads heavy rain, channeling water to its roots, making it a vital component of wetland ecosystems. The tree’s ability to coppice cleanly supports rapid regrowth, historically utilized by Berinese tribes for sustainable timber and restoration projects. Its wood is prized for crafting durable structures and tools, and its presence indicates stable, nutrient-rich soil, making it a key species for agricultural and ecological surveys.

Lifespan

Lives 80–120 Geban years. Rapid coppicing growth in the first 10–15 years. Reaches maturity at ~20 Geban years and produces viable seeds annually in wet seasons.

Uses

• Timber: Coppiced wood harvested for durable structures, tools, and furniture; valued for water resistance.
• Ecological restoration: Rapid regrowth ideal for stabilizing eroded riverbanks and deltas.
• Indicator species: Presence signals fertile, water-rich soil for agricultural and survey use.
• Cultural use: Berinese tribes carve rainwood bark into ritual totems symbolizing renewal and resilience.
• Guidance: Coppice during dry seasons for clean cuts; avoid harvesting during stellar disruptions when wood may be brittle.

Notes

The Berinu Rainwood’s water-channeling bark and coppicing ability make it a cornerstone of Berinu’s agricultural and ecological stability, particularly post-Fracture (~2,000 YBM) when it supported recovery efforts. In coastal Thazvaar, overharvesting during the Warlord Eras (~500–17 YBM) reduced populations near contested zones. Expedition teams should monitor for tidal flooding, as saline surges can weaken younger trees. Its limited range outside wetlands restricts its use in arid or upland biomes.
