The Tunnel Warning

The Tunnel Warning
An Underground Threat
A wounded dwarf reports that an Urgal army is approaching through abandoned tunnels. The danger is more severe than a surface invasion because the enemy may emerge inside the refuge.
The Hidden War Revealed
Ajihad identifies Orthíad as the renamed gathering point. The Urgals’ migration, alliance with Galbatorix, and unknown numbers reveal a coordinated campaign.
The Defensive Preparations

The Defensive Preparations
Closing the Passages
Eragon collapses tunnels with magic while dwarves reinforce the openings. The defense balances immediate survival against the danger of trapping the city or directing the Urgals toward vulnerable settlements.
The Armies Assemble
Varden soldiers and Dwarves form battalions around Tronjheim. Hrothgar gives Eragon Dragon armor, turning his unusual status into a visible military role.
The Opening Assault

The Opening Assault
Fire and Arrows
Urgal forces emerge through the tunnels and are met with pitch, fire, stakes, and arrow volleys. The defenders inflict heavy losses but cannot stop the stream of reinforcements.
The Lines Break
The Urgals overcome the first barriers and force the Varden and Dwarves into direct combat. The battle becomes a contest between defensive skill and overwhelming numbers.
The Rider’s Battlefield

The Rider’s Battlefield
Aerial Strikes
Saphira carries Eragon over the conflict, allowing them to attack archers and exposed flanks. Her Dragon armor protects her body while leaving the wings dangerously vulnerable.
A Wider View
From the air, Eragon understands that the three battles are all turning against the defenders. His unusual mobility gives him knowledge, but not enough power to reverse the entire war alone.
The Battle’s Reversal

The Battle’s Reversal
Durza’s Intrusion
Durza enters Tronjheim through a tunnel and threatens to capture Eragon. His arrival reveals that the battle has been breached by a force more dangerous than the Urgal army.
Collapse of the Enemy
When Durza dies, the spirits leave him and the Urgals lose their unifying command. Their army turns against itself, allowing the Varden and Dwarves to survive.
