The Dreadful Treant Civilization's "Giant Tree Ecosystem" was truly one of that Top-Level Civilization's defining features.
During the subsequent preparations leading up to war, it was not only the five Giant Tree Worlds that clearly possessed the standards of Large Planes that descended upon the Land of Exile.
Thousands of "Tree Worlds" also descended upon this Dimensional Battlefield.
These Tree Worlds primarily corresponded to the Dreadful Treant Civilization's Giant Plant Trees of Level 4 and above, with plane levels ranging from Small Planes to Medium Planes.
One Tree, One World; One Tree, One Legion. This was perhaps the Dreadful Treant Civilization's greatest defining feature.
The Plant Legions the Dreadful Treant Civilization brought into the Land of Exile Dimensional Battlefield generally relied upon these outrageously massive Giant Plant Trees.
Most striking of all, opposite the boundless Metal Frontline forged by Saine's Mechanical Legion stood an endless dark-green forest bulwark belonging to the lush Dreadful Treant Civilization.
These forest frontlines constructed by the Dreadful Treant Civilization differed from those built by the Elf Great World during wartime.
The Ancient Tree Frontlines constructed by Elf Civilization carried obvious elements of life, sunlight, vitality, nature, and more.
The Dreadful Treant Civilization's forest frontlines, however, possessed an additional air of strangeness, absurdity, distortion, and chill.
After all, it was a Top-Level Plant-Type Civilization with extreme attributes, unlike ordinary Plant Civilizations.
The two Top-Level Civilizations did not continue endlessly constructing Bunker Frontlines within the Land of Exile.
About seven hundred years after the legions of both civilizations entered the Land of Exile,
the Mechanical Civilization Legion under Saine's command was the first to launch an attack against the Dreadful Treant Civilization!
This was a probing offensive led by Dominator-class Beings.
As the Dimensional Hegemony of Mechanical Civilization, the first shot was naturally fired by Mechanical Civilization.
