Great Tree
Somewhat akin to Yggdrasil, the World Tree of Norse mythology, this tree grows at the center of TwinWorld.
Value to the Fayrie
The Great Tree allows provides The Fayrie with food and resources. It bears on its branches fruits of many kinds, and its wood is valued for its lightness and strength. In its bark are nodules of precious gems and valuable ores, brought up through roots from the deeps below, allowing access to many valuable minerals that would otherwise be inaccessible to the Fay.
Value to the Zarth
Although the Great Tree is most visible above ground, Zarth also revere it for the steadying effect the roots have on the soil and rock below the ground. Zarthaanc is a chaotic and dangerous place, and much of the Zarth effort goes into hewing stability out of Turmoil. It is told that the Zarth lived at first nestled in the roots of Great Tree, but as they grew more bold roamed ever further and further abroad.
