First Pinecoast Invasion

The First Pinecoast Invasion was the first of two assaults on the kingdom of Pinecoast. Both attacks were orchestrated by the Lich King's March (the armed forces commanded by the Lich King).

Background
As of now, the incentives of why Pinecoast was prioritized and assaulted over the other five kingdoms (Oakwald, Tir'ak, Giotuea, Skrindlberg, and Grundryn) is unknown. However, it is reasonable to theorize that the city may have possessed some key resource for the Lich King's March, or a threat that had the hidden potential to hinder the droves of undead.

On a different note, there was no warning of an assault on Pinecoast. No hints or interceptions allowed the living to gain the upper hand against the undead.

Assault
The invasion started in a nearby Feywild patch from Pinecoast. Swarms of machines rolled into the lush forests and began spewing their toxic secretions. Both outnumbered and significantly damaged, the residents of the Feywild patch were evacuated into Pinecoast. Some, however, fought alongside the living, possibly giving the defense a watershed advantage.

The undead assembled the pylons for a shielding dome to protect the leading commander of the assault. Reports say that a powerful band of adventurers lead by Abe Lincoln swept through the vitals of this shield and made their way to the leader.

While the events of the confrontation with the invasion leader are unclear, many witness reports suggest that the leader "...fled with cowardice and desperation."

During the Second Pinecoast Invasion, it is likely that the previous invasion leader also commanded this invasion.

Aftermath
The First Pinecoast Invasion resulted in a defeat for the Lich King's forces. Druids, making up a significant number of individuals in the Pinecoast region, helped restore the Feywild patch. A Treant, Viola, and Gioe Oaklips successfully eliminated Pewp Pu after the battle due to his unruly and suspicious behavior towards Abe Lincoln (it is confirmed that Pewp Pu did significantly assist in the success of the First Pinecoast Invasion).

This victory was short-lived, soon in the future the Second Pinecoast Invasion takes place and leaves the city in ruin.
