Hi Zedturtle, here are my opinions (tm)
First: as I already said earlier in the thread, I like the Hope expenditure as a way to keep the "spellcasting" from going overboard (in other words, I like it rare).
Second: that last lore had me dubious.
The first power is a bit too weak IMO: 1 Hope for 3 rounds is a killjoy. I would make it "for the whole scene or 1d6 hours": if magic is costly, let it be great.
The second power, "Vision of the Other Side" can easily wreck adventures. If you can spot the shadow's servants with a spell, intrigue and investigation adventures are difficult to pull off. And remember that Gandalf didn't spot the One Ring, and Saruman went undetected from Gandalf, Radagast and the whole White Council. I'm sure we can say that Saruman wasn't yet in the thrall of the Shadow, but how many times can you pull it on the PCs before they grow frustrated and say "if you don't want such spell in game, don't give it to me"?.
That said, I really like your work. Just that last one is a bit off in my opinion
