Thread Storm is the kind of skill that makes Hornet look less like a traveler and more like a silk-powered blender. In Hollow Knight: Silksong, this ability lets her unleash a storm of silk and carve through enemies in a flurry of slashes. As of 2026, the route to it remains a vertical puzzle box in Greymoor, and the prize sits at the highest point of Craw Lake. The catch? The balloons that lift Hornet toward the sky are not exactly eager to help until someone deals with a room full of crows.

First, Wake the Balloons

If the balloons are missing, players must unlock them before dreaming of the top. From Far Fields, head into Greymoor and run right until a dock appears, surrounded by water. Swim across, climb to the Crow’s Nest entrance, and head inside. Down goes the path, then up go the platforms, until Hornet reaches a large room. Waiting there is a boss fight against a hoard of crows—a feathered committee with strong opinions about trespassers. Trust me, the crows are not handing out participation trophies.

Once the fight is over, hit the lever in the higher room. This spawns balloons everywhere, turning Craw Lake into a much friendlier elevator shaft. No sweat—unless players count the swimming.

The Climb to Craw Lake’s Highest Point

Back at the dock, the real ascent begins. The balloons are moody little lift operators who only clock in after that boss fight, so players should treat each jump with respect. The route is straightforward once the rhythm clicks, but it has a few nasty spots.
