How to reach Marus Seru
The best way to reach Marus Seru is by first traveling to The Nexus. Once you're in The Nexus you'll want to take the northern most exit which will take your to The Netherbian Lair. If you need to see a map for this route, use the picture above for some guidance.
Once you're in The Netherbian Lair you'll find the Marus Seru zone line a little bit south and then west. Basically once you hit the large central column while running south through the zone, you'll wanna turn down the path leading west. Need help finding this location still?
