"This will keep you invisible for a few minutes when you drink it," she said, before handing the skin to Fendros. "The necromancer may try to detect our lifeforces as well. I could hide and watch from the outside when we lay the ambush in case of that." "I was just thinking on that," Fendros responded. "Is there any way we can hide ourselves from such detection?"

"We'll have to rely on our quarrel's complacency then, and a bit of luck. Let's set up and wait for a few hours."
