River Mithonnen
The great River Mithonnen is the very center of the Delann way of life, and the beating heart of the Delannwood.
The Lake Laessendhith
It is born in the lake called Laessendhith, or the "Cradle of Mists" which is considered sacred to the Delann and not used for conventional daily life, but instead held aside as a source of great bain ("wonder/beauty") for the Delannfolk. It is not uncommon to find many wood elves along the shores of this lake at all times of day and night, each in the curious state of wonderment that elves call bain (see Bain and Elo! for more details).
Hithlain
In the shallows of the river's expanses grow reeds whose outer hulls protect bundles of rich, silk-like fibers of a pale silvery-grey hue. The Delann call these fibers hithlain, or "mist-thread" and consider them a gift of Mithonnen to them. These fibers are extraordinarily strong, and when woven using the arts of the elven craftsfolk among them, result in cloth and rope that are both extraordinarily strong and very light and thin.
This cloth and rope both have a pale, silvery-grey color which practically becomes indistinguishable from the banks of fog and mist that regularly roil off of the river, allowing entire groups of the Delann to simply fade from view by entering the mists. The padahithir ("mist-walkers") of the Wardens all wear great cloaks crafted of this cloth.
The Delann will craft garments of hithlain for non-elves, but will not sell raw bolts of the cloth or spools of the thread, and will not sell garments in bulk.
