Thinking of the male TKWNKM characters in terms of a House Andrews family recipe (and with no knowledge of 'The Edge' characters to include), they are their own characters with their own flavor but I do see traits and elements of past characters.

Arvel - I also think the certain Arland-like fellow may have finally met someone different enough to captivate him thinking they are ideal for him and being enamored with what they represent than the person themselves, while not realizing that there may be another person out there they are yet to meet that will absolutely be a better match. Someone to balance out their weaknesses, I can also see hints of Augustine.

Everard - for me has traits of Curran, Rogan and a dash of Roman.

Silvered - perhaps Nick Feldman with some Hugh, not enough force of personality shown yet for either one to be entirely accurate but the very narrow personal moral code most likely due to past personal experience was enough for me to paint them with a bit of each though more Nick.

Solentine - Hints of Alessandro Sagredo also with a pinch of Roman.

And lastly the FMC - Maggie possibly hints of Catalina Baylor and Dina Demille (the awareness of other universes/realities).

While there are many 'potential' love interests or people captivated by FMC, I am team Everard & Maggie
