How much magic?

One of the considerations I have made about the Hawaiian Noir setting is how much magic? At first I was thinking balls out D&D/Weird Adventures level of magic. But I think I'm going to go with a more limited subtler level. Like CoC, where magic is unknown/thought not to be real by the vast majority of people. Its out there, and even a few in government know about it. Some governments secretly tried to harness it for their goals. But magic, and spirits are fickle things. It didn't always work out well. Certainly not enough to change the war let alone the outcome. More evil bent creatures, and such did have a heyday in the chaos though. Now that the world has returned to a relative calm. They have retreated back into the shadows. Weaving their conspiracies and plots to torment the earth.



Oh, as a side note.
