Exclusive: New Clues from Nightshade's Shay Doran

If you're following along with Shay's Shadow Days, I've got an exclusive puzzle for YABC readers to figure out.

I just received this book from Shay: Roundabout Papers by W.M. Thackeray

Inside I found these pages:

The first page says:

"The searchers in many small company scour with a dangerous strength"

The second:

"Alistair had his men journey the great world by sea, looking for her immortal grave"

So, Nightshaders, what does it mean?

If you think you know, post your ideas on Shay's Facebook page or make a YouTube video and tag it with the label "Nightshade" so everyone can see what you discovered. If you help Shay unravel his puzzles, you might become a character in the upcoming prequel that will be given out for free to those who pre-order Nightshade. 

Let me know what you think!
