There are a lot of hidden things in the Forgotten Vale, but there are two that still elude me: The Sapphire Paragon and the Shellbug. Can anyone direct me to their locations?

Sapphire Paragon is near the Amethyst Paragon, but up the waterfall, you'll see a staircase on the mountainside across the river.

Thanks! How do I use them?

Right across from the Sapphire Paragon (pretty sure it's the Sapphire), there is a gate with a paragon slot. You put them in and the gate opens to different locations. The Ruby one is the one you'll want to be excited for.

Thanks a lot!

I believe the Shellbug is in the Forgotten Vale Cave, right near where you first enter the Vale. I think it's on the right side, check your local map for the marker.

Wow, I searched the entire LEFT side

I just found a second Shellbug located in Sharpslope Cave.

Can someone tell me where Volume 4 of the falmer books is?
