I had begun reading a short story or a novel on gutenberg.org couple of years ago (Those who don’t know, it’s a site where you can find all kinds of public domain ebooks.) The story was set in a distant future where people time travel to various time periods of the past and live there and thereby drain resources of the past. There was some kind of structure called time dome or smth like that. It read from the pov of a guy called Ted, Tom or Taylor. I had to uninstall my browser and therefore lose all data. Tried to find it, but couldn’t. It was interesting enough for me to remember even today.
Edit: I can’t believe this myself, but I somehow found it and it was actually reaalllyy easy. Took me like 30 seconds. I just went to Project Gutenberg, opened the books about time travel section, scrolled down and down and there it was… Tyrants of Time by Milton Lesser. Even though I read it in Gutenberg.org, not once did I look up in Gutenberg itself. I made social media posts, googled it, asked chatgpt and all that. I have no idea why I didn’t look it up in Gutenberg itself. And the structure I called ‘Time Dome’ was actually Eradrome, it’s a place that facilitates time travel. And the protagonist is actually Tedor Barwan. Damn, I’m really stupid!!
I read a book that a friend lent me in high school where orcs were the protagonists. They found a portal or time travel machine (can’t remember which) that let them travel to modern times and comandeer modern military equipment like assault rifles, tanks, and helicopters. I always wanted to finish reading it, but returned it before I could. I’ve tried searching for it but have come up empty handed.
Doubtful, but it could perhaps be The Nightmare Stacks by Charlie Stross?
Spoiler
It has somewhat orc-like elves invading modern Britain.
Not the book im looking for, but this does seem entertaining in the same kinds of ways.
