Far Eastern Cliff.
As the most conspicuous dividing line on the continent, the Far Eastern Cliff was not a wall that had abruptly appeared upon the ground. Rather, it was the collective name for a sprawling mountain range of rolling terrain, immense elevation changes, steep mountains, and perilous peaks.
The terrain here was so fractured that nothing but birds could pass through it. Combined with the active crustal movements that built up tremendous pressure beneath the ground, magma would occasionally erupt thousands of meters into the air before raining back down.
Even without the dragon race building defenses here, the Far Eastern Cliff was an impassable natural barrier. Earthquakes, lava, and smoke had turned this place into a forbidden zone for life.
Clink, clank...
This was the sound of undead laborers smashing apart igneous rock. They tirelessly dug traps and buried single-use magical items within them as land mines. Thanks to the magical rune armor Ainz had given them, these undead laborers did not have to worry about the heat of erupting magma setting them alight.
Supervising and assisting their work was the dark elf Mare. He waved the staff in his hand, freely reshaping the earth and making the environment even more dangerous and precipitous. With even the slightest explosion, he could trigger devastating collapses and torrents of rock.
"Are these the only people we have deployed here?"
Beside the busy Mare stood a handsome man with a tense expression, who had not forgotten to straighten his splendid attire. He was the humanoid incarnation of the Brightness Dragon Lord, sent here on the Dragon Emperor's orders to ensure that the Far Eastern Cliff's defenses were flawless.
Hearing the Brightness Dragon Lord's question, Mare did not answer slowly in the timid tone familiar to the people of the Great Tomb.
