Just to expand on what I said..
brigand lair, blood 1, not worth it
devils den, blood 2, probably good if you have a blood mage (which you dont,
)
forest of pain, blood 2, produces a nature gem each month so that makes it worthwhile in my book
inkpot end, death 0, I dont think you have to search for level 0 sites so it shouldnt be this
the demon gate, blood 3, probably good if you have a blood mage
the lesser abyss, blood 1, probably good if you have a blood mage
the prison of hearts, blood 3, it produces 40 gold a month
the shaded lands, death 0, probably not this
the vale of infinite horror, blood 1, increases misfortune and has a chance of horror marking any unit there.. so it doesnt do you any good to find it except to know never to store anyone there
tower of the devils bride, blood 1, probably not good even if you have a blood mage
That looks like it. I dont think I'd bother with acashic record personally
