Szarekh was right when he said that the Jaffa of other Goa'uld were weaklings and decadents, too concerned with their honors and too little with war. A Hydra operative sat next to the stunned Jaffa, scanning his memory—he was a high-ranking Jaffa with a silver symbol on his forehead. Intelligence operatives were extremely experienced at this sort of thing, as he had been doing it for a long time. No one could suspect anything was going on, as the Hydra base was located in a local brothel. After it was over, he would download information about sex with a prostitute, and the man would not notice a thing. This was the best way to extract information from high-ranking members of the Goa'uld army. The operative quickly generated data packets, managing to modulate the desired "questions"—addresses he knew, the location of his master's combat forces, and so on. Old methods of information extraction had acquired new possibilities.
Having completed the entire operation, the agent calmly returned the Jaffa to the place where he had spent time with the prostitute. He would suddenly awaken, realize he had completed all his duties, and then leave. This type of work required contacts with local prostitutes, so he worked only with their "matron." He erased the girl's memory of his presence. Now it was time to leave and leave the crystal with the data for the other groups. Hydra maintained a decentralized network; some people changed their faces so that if one was caught, they wouldn't betray the others, even by their face. Of course, there were self-destruct systems, but vigilance was essential.
The agent returned to his home and began taking orders. He was a blacksmith, and very good at his job. An important man, he had many orders and many connections. In fulfilling his duty, he actively spied against Nirrti's forces, sending invaluable information that aided his cause.
"Daddy's here," the children shouted joyfully.
The agent smiled. Despite the work he did, he still found a way to do something human. He had his own offspring, and when he left, he would evacuate his children and his wife. His duty to Sareh was absolute, so he didn't tell his family what he was doing; it was simply dangerous.
"Here, strong man." The Hydra agent took his son in his arms.
They were taught to completely infiltrate any society, merge with it, become one. To move like everyone else, and to think like everyone else.
The goal was to create autonomous cells that could sustain themselves. He had already done this, employing a group of loyalists who were gathering information about various Jaffa groups, their habitats, and their activities. The Jaffa were the best sources of information available.
They scanned their memories and even modified them; if necessary, they could install a program to kill specific individuals. Killing Goa'uld is pointless, unless it's an explosion that completely detonates the host's body. However, assassinating Jaffa officers by another Jaffa officer is far more promising, or, for example, sabotaging the Huttaks. The applications of memory scanning and implantation technology are limitless, and the agent used it to subjugate enemy soldiers for subsequent destabilization.
Hydra acted slowly, deliberately, building a network of agents capable of overthrowing any government on any planet in a matter of days. Of course, that wasn't the mission of this particular agent, but the intelligence potential was limitless.
"Cut off one head, and two will grow in its place. You will strive for the same goal with many comrades. You will not know them, nor will they know you, but the one goal is to ensure that Lord Szarekh crushes his enemies."
- They talked about it at the intelligence school, something he had been living with for many years.
