OK Captain America.
I understand. Just some advice for your next game: give the players puzzles or hints to find their way through a game, or give temporary NPCs. Players like to be the main heroes themselves and figure things out on their own. They can feel pretty unimportant if an NPC is guiding them through everything.
This was a problem for my first D&D Campaign I started. It's very tempting to make "DMPCs" to lead a party and have your own roleplay input in a story with the heroes. I had my players led by a pirate captain named Dana, but eventually my players felt I was keeping them on rails by her leading them around everywhere. Eventually, I gave them free reign and it became better. In the future, I recommend the same.
You've been excelling in playing the villains and NPCs. A DM should focus on that; helpful NPCs and villains with plenty of personality. Interesting character ideas I keep to stuff like shopkeepers, miners, workers, etc. and suddenly the world feels more fleshed out.
Just my advice though. I look forward to this Isotix chapter.
