Note that there’s a miniboss in Lost Verdania known as the Palestag. That foe also spawns light orbs that you need to catch. Assuming you’ve found every single light orb in the zone, make your way to the top-middle section of the area. There, you’ll be able to enter a house. Inside, you’ll face the Green Prince.

The Green Prince boss fight–i.e. Clover Dancers–is akin to the Cogwork Dancers encounter from the Citadel. But there are some notable differences:

• There’s only one target–the Green Prince–not his light clone.
• The powerful ability performed in the middle of the room causes a cyclone that rotates.

Once you’ve beaten the Green Prince, Hornet will wake up back in the ruins of old Verdania. There’s a glowing item nearby. Pick it up to acquire the Conjoined Heart. This is a memento that’s part of your collection.

That does it for our Hollow Knight: Silksong Verdania Green Prince guide. Since you’re fairly close to the endgame now, you might want to check our (spoiler-filled) endings guide in case you want to know how to conclude the campaign.
