Three miles west of Bastion, the swamp was being completely redesigned.
Warlord Gorak stood knee-deep in muck, pointing his pickaxe like a conductor's baton.
"Deeper!" Gorak roared at a crew of fifty Troglodytes. "The Sun-Men ride heavy beasts covered in iron! If the trench is only waist-deep, they will just step over you! Dig until you hit bedrock!"
The Troglodytes were essentially human excavators. They tore through the mud and clay at terrifying speeds, creating massive, jagged ravines hidden beneath the swamp water.
But a trench is useless if the enemy can see it.
"Elder!" Gorak yelled over his shoulder.
Old-Shell, the massive Shell-Kin elder, lumbered forward. His shell was laden with massive slabs of slate and porous rock hauled from the Deep Roads. With a heavy grunt, Old-Shell and his kin laid the stone slabs precariously over the tops of the trenches, creating fragile 'bridges.'
Then, the final touch.
