Heaven's Ash

Rising above the surrounding hills and forests like mountains in their own right, the grandest emanations of Syjéral and the greatest of the kami serving the daughters of Sylithandríël are the lórréra, the World Trees.

Far above any dryad, naiad, or lesser emanation, the scattered handful of lórréra work together with the mechal elementals produced and commanded by the dweomerbergs to manage the planetary ecology.

The World Trees, like the lesser dryads, are trees at heart, albeit unusually large and healthy ones, optimized to produce through their natural processes the energy needed to support their other functions. Each of the lórréra is, beneath the bark, an unthinkably complex biocomputer composed of complex arrays and meshes of lignoneurons laid down within the xylem. This system and its animating intelligence are sufficient to model in real-time a complete picture of the lands, woods, and waters around the lórréra, and make such adjustments as the model calls for to maintain stability.

The lórréra exist in a world of continuous communication. They exist as major relays within the same delicate electromagnetic tapestry as the other mechal elementals, with metallic deposits embedded in their lignoneuron-stived xylem serving as their antennae, of course, but more subtly they are participants in the complex web of ecological communication around them. In this, the obvious bluelife bioluminescence is the least part; the intertwining roots and rhizomes of a mature lórréra can cover half a continent, and in doing so, touch all the life thereupon with chemical signals of breathtaking subtlety.

Is it any wonder, then, that we, too, should have learned to communicate with them, and they with us? While thaumaturgical lore – the knowledge of the mechal elementals and the art of reading and commanding them – remains well documented, there remain only fragments of its origins, and that of much other ecological and silvicultural lore – in the shamanic practices of the Emergence, going back into the Gloaming, when eldrae first learned to underhear the electromagnetic whispers of the World Trees, and to attempt deeper communion with nature by crude pagan rituals involving the consumption of their sweet, nanite-rich sap.

(It is also from fragments dating from the Emergence that we have the tale of one Sárvis, called “the Ill-Wit”, who commanded the tribe of which he was king to fell one of the World Trees that he might build for himself “a hall like none other that ever was, or ever would be.” Upon attempting this, his tribe were plagued by ills “as if all the spirits of nature rose against them”, until Sárvis pledged himself to be slain among the branches of the offended lórréra to appease its wrath. The surviving fragments do not record the success or failure of this gambit, or whether or not his people survived.

None have attempted to repeat such grand folly in all the centuries since.)
