One of the drow women at the front of the cart glances back, seeing Diadra awake, then says to her partner, "The elf's awake. Should we do something?" "Nah, she's probably harmless, tied up like that. Leave 'em."<br/><br/>Diadra will notice, however, that unlike her other captor, these have less skill with ropes. A little effort, and she might be able to slip free.<br/><br/>(You can take 20 on escaping, and slip free, though it'll take a while.)
