Reach a worm burrow on the 4th cursed world

Reach a worm burrow on the 4th cursed world 'We tumble as it swallows, but grip the slick walls as best we can - Oh! - to reach the gizzard still awake. Our lungs gurgle. The slime clogs our noses and stings our eyes, though in this warm darkness, we are already blind.' Follow a Titan Worm as it swoops across the planet. Use the Target Sweep to find the holy ground where they retreat to the planet's core. Find this Titan Worm burrow near the fourth rendezvous.
