Hollow Knight

After defeating the 3 dreamers and headng to the black egg temple, you see the vessel of the radiance, you either kill him normally ad become the new perfect vessel or use your Dream Nail to enter his dreams and slay the radiance himself, making Hallownest "Immortal" again, but the damage has been done. maybe elderbug can revive hallownest :) DO NOT USE THE SOUND OR 2.0 ANY RADIANCE WILL SPAWN AT YOUR DOOR
