This page offers a guide on where to locate and how to complete Path to the Wind-Blue, which is a Mystery located in Grantebridgescire.
Speak to the Norse Soldier
This Mystery can be located on an island east of Middeltun. The Norse Soldier will explain that he is blind but is seeking Wind-Blue, which is a paradise higher than Valhalla. He will first ask you to help him light the braziers. He will lead you along a path and you’ll need to use a torch to light the fires along the way. There are three braziers to light as you follow the Norse Soldier. The final brazier is on the riverbank, just across from Soham Hideout, which is an enemy ridden camp.
Tip: You can clear out Soham Hideout beforehand and it won’t affect being able to access or complete the Mystery. You can also raid the area using your longship crew!
After lighting the third brazier, take command of the small rowing boat to the right of the brazier and row yourself and the Norse Soldier over to Soham Hideout. When you arrive on Soham Hideout, you’ll need to clear out all of the bandits around. There are a lot of them, but they’re relatively weak and you can easily one-shot most of them with an arrow to the head. It’s also recommended you stay relatively hidden in this area so you aren’t overwhelmed by enemies. Taking out the bandits one-by-one using your bow and hiding in the brush is a stealthier approach but might be easier than running in like a juggernaut.
There are also a couple of Wealth points in this area. In the central hut, you’ll find some Huntsman Breeches in a chest. The enemy named the Hurler will also be of value, since when you kill him, you’ll be able to loot him for a Carbon Ingot.
When you’ve killed all enemies, speak to the Norse Soldier to complete the Mystery. You’ll earn 1,200 EXP for completing the Mystery and there’s plenty of loot and supplies to grab in the area.
