Trod
The Trods were created as a weapon but in the fullness of time their value to nurture the land through which they pass and the people that use them has been realised by The Conclave.
As the Stridings migrate along the Trods the unconstrained Spring Magic which is the heart of the Vallorn is slowly leached away. The longer the Trod and the larger the Striding the greater the effect. However, this magic is not just bled into the ether but is returned to the land and in some small the people that travel the Trod.
Swords
A Trod starts and ends at a Vallorn. As a Vallorn grows more powerful as the Navarr advance closer to its heart, successive generations have chosen to travel further to weaken it sufficiently before any attack is attempted.
Stridings routinely move from Trod to Trod, to ensure as much of the Vallorn's life-force is depleted before the attempt the dangerous journey back towards the Vallorn.
At the fall of Teruniel the unstoppable advance of the Orc foe made this task virtually impossible. The founding of the Empire was the beginning of a sea-change in the Navarri ability to fight the Vallorn.
People that that use Trods; some of which have become well worn roads, feel refreshed each morning as if they had spend a night in the finest beds.
In addition crops on land through which a Trod passes seems much less prone to disease and the failure rate of alchemical preparations made with herbs grown near a Trod is measurably reduced.
New Trods can be created; however, it takes a great Ritual and no new Trods have been pioneered since 382 AE
