SPOILER on Homestead under attack.
Your destination is in Silverglen itself, near the top of the map in NE. The quickest route is from the teleporter S of Goblin village.
From there take the road going north to the temple. When you get at the entrance, you'll get further instructions from a familiar face.
It's the Lucella map, not Silverglen which is just a town in the Lucella map.
destroy the giant bloodstone to kill the void demons and therefore stop the attack on your homestead
