I've been thinking about the Berserkers ever since you found their shield at the Lookout, when you were helping me with Gronckle Iron. I think it's past time that we tightened our defenses, and we should start with Berk. The caves under Berk could be a problem; we haven't explored them very much so Dagur could use them against us.
I think some Whispering Deaths might have opened some tunnels to get there. Can you look for a Whispering Death tunnel in Berk to get to the caves?

Here are the caves! Wow. This is a bit dark, don't you think?
You'll need to be careful to not step on the animals here. You might have a hard time adjusting to the light, but the animals that live in caves have evolved and adapted over the years to be able to function in low light!
Bats, for instance, use echolocation to 'see' where they are going. Bats emit a high-pitched sound that humans cannot hear which bounces off objects. THe sound is then received, giving it information about the object's shape, direction, distance, and texture. Bats are nocturnal. they are active at night and sleep during the day.
Will you explore the cave and see if there's anything interesting down here? Be careful!
Well, those spiders are really creepy! These spiders look like they have evolved to live in caves. Animals that only live in dark caves are called troglobites. They have highly developed senses of hearing, touch, and smell!
Are you wondering how troglobites eat down in these caves? Sometimes, excessive rain can wash plants, leaves, and other nutritional things into caves. Another food sourse is bat dung - or guano, as it's called scientifically. Fungi and bacteria in the caves decompose the guano into essential foods and nutrients.
Don't get caught in the webs, [your Viking's name]. Will you explore the cave and see if there's anything worrying down here? Be careful!
Wow, there's an underground lake here! That's very interesting! There must be an opening under Berk that allows the ocean water in. I bet Berserkers could get inside the cave and get to the village.
You should stop here and catch some fish. You won't find fish like this anywhere else!
Thank you for helping out, [your Viking's name]. Why don't you take one of these Whispering Death eggs for safekeeping? I'm sure you'll be able to train this dragon well.
