Esper Node Pyramid
From Drunkapedia
From the Tainted Ley Line Nodes quest introduced in Shattered Lines.
Located at 62.0N 18.0E, southeast of Mount Esper. A short run south from the Neydisa Castle. There is a Neydisa Castle portal near the drop in Holtburg.
The pyramid's light is strengthening, but there will be a long way to go before it is restored. It has not yet reached half strength.
Search for Blighted Oak Golems in the area surrounding Mount Esper, they drop Blighted Mana Crystals. Give their trophies to the Node, see A Field Guide to Tainted Nodes for details.
