"Let me stay here for a while, I have to do a few things," he paused, looking around before adding, "I'll give you a few blueprints, deliver them to the artisans, and let them work on the essential pieces. If they meet anything they can't make, leave these for me to do."
"This…" she blinked while her mind realised something, "do you plan to stay here for a long time?"
"One few days," he didn't look at her while examining the mountains, "make sure they built as many parts as they can. Our survival odds depend on these…"
"Ok," she got the blueprints he gave her, turned around before pausing for a second, "take care of yourself, will you?"
"Don't worry, we aren't in any danger," he paused here while muttering to himself, "at least for now…"
Thinking that the enemy would leave them alone and trapped here without harassing them was delusional. The enemy would give them little time before they'd start sending lots of monsters here to wear them down.
