The Man with the Golden Torc by Simon R. Green

Marvel later reveals in the Marvel Fact Files that the 'Many-Angled Ones' are also known as the 'Old Ones' and therefore Shuma-Gorath is the ruler of the Many-Angled Ones (being the 'Master of the Old Ones' per the Marvel Handbook Horror 2005). In The Thanos Imperative, Shuma-Gorath is revealed to be a member of the Many-Angled Ones.

Countless worlds and dimensions worship the Many-Angled Ones, have been conquered by them, or destroyed by these ancient beings.

They are beings of chaos, destruction, corruption, and evil. It's not clear what is their origin, though one theory is that just as demons were created by the nightmares of mortals, so were the Many-Angled Ones created by the nightmares of demons themselves. In the Marvel Multiverse, the Many-Angled Ones are Eldritch-like entities that live outside the universes, in the space between the infinite number of realities and who appear to exist simultaneously in many planes at once. As a result, when they manifest in our universe they appear as disconnected floating body parts of some larger beast that is complete in the higher dimension (similar to how a three dimensional being would appear in flatland as its parts pass through the plane of that two-dimensional world). The many-angled ones exist in a space with more dimensions than our own hence, they appear to be many angled. In the comic, the many-angled ones have a dastardly plan to impose rigid geometrical order on the whole universe, essentially reducing it to clockwork. However, they appear somewhat different from the Cthulhu Mythos entities. In Zenith they are known as the Lloigor, a direct reference to creatures from the Cthulhu Mythos. This spy yarn is packed with enough humor, action and plot twists to satisfy fans who prefer their adventure shaken, not stirred.They first appeared in Grant Morrison's story Zenith, which appeared in the British comics anthology 2000 AD. Declared a rogue, Eddie teams up with short-tempered witch Molly Metcalf to find out why he's been betrayed.

Then the family matriarch sends him on a mission that turns out to be a deadly setup. Meet Shaman Bond, aka Eddie Drood, scion of the ancient Drood family, devoted to 'protecting humanity from the forces of darkness.' Protected by the 'secret weapon' received at birth by all members of the Drood family a magical gold torc (i.e., a neck ring) that turns into a suit of nearly impervious golden armor Eddie faces arcane dangers with healthy doses of wry self-confidence and sarcasm. Readers who recognize the pun on Ian Fleming's James Bond title, The Man with the Golden Gun, will find the secret agent in question has more up his sleeve than a fancy car and some high-tech gadgets in this first of a new fantasy series from bestseller Green (Deathstalker).
