The anti-Simurgh (deadlyham)
Beria was the head of the Soviet secret police under Stalin.
If you're going to name something and it matters, it's a good idea to Google the name first. (Advice that Grue could have used too.)
The word was taken directly from Sindarin. Given that Tolkien was obsessed linguistics I'm sure the word has a particular root and reasoning for its spelling. I'm also pretty sure it is pronounced differently from the name.
I get all these omake ideas and this is what I end up writing. I still need to figure out an omake where Taylor presents Joe with a wet, lumpy sack. I was thinking about Authoritarian Communist Elves and secret fantasy police. One thing led to another.
Omake:
I felt the forge grasp for a gigantic mote in the same constellation as Dwarven Craft and Elven Enchantment. I braced myself for the power, remembering the last mote that was close to this size. I still wasn't prepared. It was beyond any of the motes I received so far and descended on me like a supernova. Unlike any of my other powers, dozens of names for this power echoed in my head, but one name resonated with Elven Enchantment, Iarwain Ben-adar, Oldest and Fatherless. This mote gave me deep intimate knowledge on the fundamental forces that underpinned magic and history of how those magics were applied since the beginning of time. Any enchantment, curse, and spell were just teasing at possibilities with this power. It wasn't only that I understood the fundamental forces of these fantasy powers, I witnessed them come into creation. This was the greatest power I ever received, and it came to me as personal memories of a jolly old man. I saw primal beings walk out of raw chaos. I cavorted with things that could be called gods. I saw the twin trees grow form saplings in all their beautiful light. The Unseen responded to my singing like old friends singing a duet, because I am an old friend to these forces. But it wasn't just joyful memories. Where there is light, there is darkness. I witnessed the darkness of the world snuff out the twin trees.
I watched the first mortals form tribes and cities. Knowing that these good things would need help against the darkness, I cavorted among them and became friends to the first elves, humans, dwarves, and many peoples of the earth. Overtime I gathered trusted allies, especially among the immortal elves, but more often I had unwitting mortal pawns. A well placed word, a twist to nature here, an enchanted treasure dropped there for an adventurer to find. All these little touches to aid the light, but none of them could shine too bright, because bright lights cast starker shadows. While I could work powerful magics, I had to be careful with my power. Letting loose the thaumaturgical equivalent of a reality warping nuclear bomb was an unnecessary when I could toss a single pebble and watch the ripples overthrow kings.
Hardly anyone knew that I or my associates worked together in secret to ensure the world ran smoothly. Our organization didn't even have a name, and couldn't, in a world where names had powers. When you ran a secret spy organization in a fantasy world, then you took any measures you could to ensure dark gods couldn't scry you. This part of the power had a lot in common with memories from my Gadgeteer mote, but with less British accents and more waterboarding hobbits.
The implications of this power hit me hard. I could hide from the Simurgh. This power didn't grant me complete immunity from precogs and scrying, but it perhaps did something better. I had experience working against near omniscient dark gods now, and I can use those skills against the Simurgh's precog power. Powerful precogs could see the consequences from a blind spot, like ripples emanating from a central point, but I could obscure that point by casting dozens of pebbles. The ripples would overlap and cause chaos in the sight of any precogs and clairvoyants looking for me. I won't be able to unleash my full technology in a great technological uplift of humanity, but I can safely influence the world beyond Brockton Bay.
I could cure case 53s! I can work the power behind their mutation, which was similar to some nastier curses. With how Case 53s were spread out across the world, going on a random tour to treat them would help obscure me from precogs further.
fake edit: Tom Bombadil was running Middle Earth from behind the scenes. This power would basically let Joe work in the world as as the anti-Simurgh, letting loose plots that have huge positive cascading consequences on the world.
