Siege of Thoringrad
After the defeat at Shadowcastle, the dwarves of Urguan routes back to their lands in the south in the city of Kal'Ithrun. With the rebellion crushed and the Orenian victory the Kingdom decided to march south to the Nation's Crossing. When the Orenians arrived they encountered the dwarven fort Thoringrad guardian the bridge
The battle started when Oren began firing upon the fortress with trebuchets and ballistas. The dwarves returned fire with both sides having little success until a traitorous dwarf opened up the gates for an Orenian charge. The dwarves alive on the battlements retreated into the main keep where they held the gate until the main keep began to crumble. The dwarves retreated into the lower bunkers beneath the fortress and waited below. Suddenly the ground opened above the dwarves however, after a boulder laced with dark magic landed above the bunker. The dwarves were routed into their tunnels and retreated to fort Indagolaf.
This loss caused the dwarves to retreat to the last fort before their capital Kal'Ithrun. The dwarves soon began digging trenches as well as the Orenians and a long series of battles in skirmishes were fought along this front.
