"Presumably!" 

"Thanks!" 

She's pretty sure that the spell her spell-like ability is like is Dimension Door. She uses it, straight down. 

Underneath the shop is, in fact, a basement. It's full of crates and boxes and bottles and jars and sacks and, in one corner, turned into a sort of nook by artfully arranged crates, is a very portly gnome. 

He startles when he sees her, and shrieks: "Mauraders! Bandits! Scavengers!" 

Lusilla props her hands on her hips. "Oh, knock it off. Firstly, I'm none of those things, and secondly, even if I were, who, exactly, do you think would come running if they heard you? Cultists of Baphomet and Deskari, that's who. I imagine whatever way of getting down here there normally is is well enough hidden by the mess your shop upstairs is, but they'll have plenty of time to find it if you keep caterwauling!" 

He glowers at her. "How'd you get in here, then?" 

She tosses her hair confidently. "Dimension Doored. I'm a sorceress working with the Eagle Watch; I'm looking for survivors to bring to safety." 

"Safe enough down here," he grumbles. "You're wrong about cultists coming running if I call; this place is soundproofed well past the point where my voice could get through; I just wanted to scare you off. I've supplies to last out the crisis, too." 

"Good to know..." Lusilla looks around. That does, in fact, look like a lot of supplies. "...If things drag on too much longer, could I come back, and maybe buy some of this off you? I mean, it looks like more than you'll need, by yourself." 

He gives her a considering look. On the one hand, this could theoretically drag on for long enough that he would in fact go through everything in this basement. On the other hand, a sorceress strong enough to casually cast Dimension Door a) is plausibly good for it, and b) could just murder him and take whatever she wanted, if that suited her. 

"Maybe," he says grudgingly. 

"On another note, d'you know what's up with Finnean?"
