The Small Grave That's Hidden

Hella told me about The Book of Ancient a while back. I was tracking it down, but I dropped my journal out on the Snowfield when I stumbled across this weird Small Tomb. You think it might be in there?

I wanted to find out what that tomb was, so I tried getting close to it, only to realize that it was impossible because of all the scary monsters around that area. You're strong enough, though, to find a way to go in there and thoroughly investigate the tomb. The tomb was at Icy Cold Field. I'll pray for your safety until you return...

I found that weird Small Tomb deep in the valley of the Snowfield. There were scary monsters crawling all over the place, so I had to run. Now I think I might have been in the right place. It was out in the Icy Cold Field. I bet the book is there!

In the tomb there was some moss, a corpse, and not much else. Looked further in but still found nothing.
