At least twenty elite members of the Syndicate lay in ambush around the log cabin, or to be more precise, around Lucy.
These elite members were clad in anti-magic armor and armed with various expensive anti-magic gear that would completely mask their Innate Auras. There was a downside to this though. Everything in the universe emits Innate Aura, the masked auras of the thieves would create a black outline against a backdrop of Innate Aura emitted by everything else in its surroundings.
The Syndicate was well aware of this point, though, and they had a countermeasure against it. Apart from the anti-magic armor, they would also hide behind a barricade made of thick wooden planks; it was built like a small, triangular, wooden hut. The exterior of the barricade would be covered with sticks and grass, making it even harder to tell apart.
