Amber's Peak is Zertormes Castle, who in turn is leader of a collection of Aslene tribes. as he liberated the plains of Margelda, it makes sense to place Amber's peak there:

Ah21 would be a niche place.

Slavery is, understandably, a red flag for many and I have some issues wether it would be lucrative at all. Grindbone is purposefully located at a river; bear in mind that bloodlings can't manifest over water. A hex in the center will work well, on W26 most of the map will be reachable by waterway

The Eye of the rose is said to be built upon the ruins of an old elven city. The most prominent elven city is Varassa, so it makes sense to place the Eye of the rose right there, even more so as it already is heartland to the Urhur Orcs and Hroka the first and the greatest.

When I read of Ravenhole, I think of Heavy-Metal-College-Parties as depicted in movies from the 80s/90s. (By no means do I think real-world Heavy Metal and violence coincides or correlates)

Lots of booze, loud music and stupid ideas. With Ogres.

Best placed in Harmsmoor, F23 for example.

The Vale of the dead is very secluded and hard to find (unless you follow the evil eye) The game itself suggests that you can place the stanengist crown here and having Scrome watch over it is only second to hiding it in the stillmist.

V45 or its neighbours are suitably hard to reach. If you feel that's too close to Rustland (Harga/Begrand) and in reach of cunning demons, move it towards Y50.

Pelagia is, of course, found on the shores of ravenland. How far north is up to you and how accessible you want to make it for your players. It does not belong on the island of maidenholm and I would not see it fitting in the south, on the coast of Belifar.

AM30 or north of that is what I'd recommend.

Not much to say here - it's a dwarven fortress in the mountains. Rumor has it that they secretly ally with the Urhur Orcs, so placing it near makes a lot of sense.

I suggest the mountains to the northwest of Ravenland, E8 for example

Zygofer's daughter and wife, Martea and Marga are here. They can potentially be of decisive help when defeating Zytera while at the same time are quite dangerous. The book talks about some form of protection or disguise in order to not be eaten right away. I removed that in my campaign.

We do know that Marga and Martea wanted to flee to wailer's hold but were diverted. They ended up with other Marcomannian dwarfs, so Stoneloom should still be near Wailer's hold. I'd place it in Y36 / X37

Vond is most likely the place for the showdown of Raven's Purge. Zytera and Krasylla are here as is the protonexus, which most forces want to see closed. Arvia wants to reconquer the Castle and a free shadowgate pass will open opportunities to start the Bloodmarches Campaign.

It should be placed at G40, at the entrance of shadowgate pass and in the direct vicinity of ruined Alderstone.

Haggler's house should be placed on the plains of Harga, in the Heartland of the Rust church and not too far from Alderstone. Placing it near but not on a body of water will have helped to provide slaves during the bloodmist, while at the same time acting as natural defense (because apart from Rust brothers, no serious army could cross the bloodmist.)

Weatherstone is most often used as an early loredump/ treasurehunt that drags players in the campaign, so place it near their starting position. If that is not an option for you,

Z27 is often picked for its position.
