If she hangs around Dia enough, she'll see the flashiness of the lightsaber eventually. It's possible Furiosa's at least heard of Dia's weapon, if she'd heard about the fighting ring thing that kidnapped a number of people a few months back. Dia wasn't shy about using her lightsabers in her match (or later presumed escape).

Still. The weapons help her feel safe in unfamiliar territory, even if she's become much more relaxed about everything she's been doing. Finding her own sort of peace while she deals with repairing her ship (having the time to have peace, relax, and deal with things immensely freeing).

"I suppose that works then." She nods, and gestures for Furiosa to lead. Dia moves silently, light sandals letting her move lightly save for the occasional shifting brush of her ankle length kilt. "So your former leader, did he build it, or simply take it over?"

She couldn't help but be curious, such a citadel reminded her of a retrofitted temple or building, particularly with how she was looking around as they moved.
