What is the NeoHospital about? What does it have to do with the plot?

During Plot: The Neopian Hospital has teamed up with the Neopian Pharmacy to help those caught up in the attacks or adjusting to being greyed out permanently. However, they will need assistance to keep up with the influx of new patients! That’s why they are asking Neopets from all walks of life to donate their time to the ongoing efforts to treat those injured in the attacks across Neopia.
