Although I am relatively inexperienced with this, let me start of by saying I truly enjoyed your article and I think it has a great deal of merit. I'm a big fan of Jude-Christian spin-offs, and this one is other-worldly enough to pass the mundane test. Well done.
H'Malach mentions that: "You are going to keep me forever." Wouldn't a being such as Ha'Malech outlast the SCP Foundation?
Slight error: in the interview, you wrote: "Does "Somech Noflim" reside is your place of origin?" I think you meant: "Does "Somech Noflim" reside IN your place of origin?"
There are quite a few interesting additions to the SCP itself, but I'm afraid that some of them might water down and distract readers from the uniqueness of the being. The whole "less is more" bit (the sword, the ability to manufacture elements, etc.).
Keep up the great work. I'm sure others on here with much more experience will have more to say, but hopefully this has been a bit helpful.
