From Guild Wars 2 Wiki
Explorer Dalta is a Priory Explorer, located near the tunnel in Half Circle Cove. Dalta and her team have dug a tunnel in order to transport the wounded to and from Oceanside Ordnance both quickly and undetected.
- We bored this tunnel to travel beneath the coast and avoid the undead. The trick is to make sure the tunnel itself stays clear.
Where does the tunnel lead?
- It opens out near Oceanside Ordnance. It gives us a reasonably safe passage to transport wounded soldiers to be treated at Oceanside when the copters aren't available.
- That's good.
- Good luck with that.
