The town is overrun by hatred NPCs - in fact, the area for corrupted NPCs stretches up to the Spirituality Shrine and its neighboring over-the-road old guard house to the North & West, SW to at least (and including) the hidden mage valley, and South/Southeast to the jungle's edge. We've searched the city, and all its islands. We've ran search grids over the entire infected area, and beyond. No Invasion Spawn. No Crimson Dragon. Just LOTS of (Hatred) NPCs. Any cue as to what to do next (other than attempt to monkey with the sigils via faction friends)?
