Fall of the Royal Capital

Siege of the Royal Capital was the besieging of the Royal Capital of the Re-Estize Kingdom by the forces of the Sorcerer Kingdom during the war between the two nations.

Background
During their war with the Re-Estize Kingdom, the Sorcerer Kingdom knew the key to a swift victory was capturing the Royal Capital. To this end, they centered their entire invasion plan around surrounding and isolating the city in preparation of besieging it. To this end, they covertly conquered the Kingdom's eastern and northern regions. By the time the Kingdom figured out what was going on it was already too late, as the Sorcerer Kingdom's forces had begun marching on the capital.

As Sorcerer Kingdom's forces headed towards the capital, the citizens were faced with a choice: flee or stay. In the end, many stayed due to them having nowhere else to go. A while later, the Royal Army drafted all the capital's able-bodied citizens into its ranks and set out to confront the Sorcerer Kingdom's forces before they reached the city. However, they were defeated and the entire Royal Army was wiped out.

After learning of the Royal Army's destruction, a defeatist atmosphere took hold of the capital. With the war having been pretty much decided at that point, those who still could fled the city while the remaining soldiers and Adventurers prepared to make their final stand here. Normal citizens meanwhile, having heard tales of how the Sorcerer Kingdom massacres towns they conquer, barricaded themselves indoors. It was even believed that some committed suicide over being killed by the Sorcerer Kingdom.

On the Sorcerer Kingdom's side; they had surrounded the Royal Capital to make escape impossible and set up a base nearby. To keep their human symphathizers appeased, they also had Eight Fingers evacuate many of the city's children. Although there was a delay due to the Kingdom launching a last desperate assassination attempt on Sorcerer King Ainz Ooal Gown, once this was dealt with the Sorcerer Kingdom started the siege.
