The power of a Siren wasn't exactly mystical, nor was it completely innate. Sirens were born with some ability, but much of it was learned with time and practice. Put most simply, it was an ability to draw out emotions. Just as a sad song sung by a skilled singer can bring a tear to the eye, the voice of a Siren could find the tiniest bit of emotion and increase it hundredfold, until the listener was overcome by the sheer intensity of it. There had to be a bit of emotion there to begin with, however. If ever there existed a man who truly had no emotions - not just one who was skilled at hiding them - then the Siren's powers would be ineffectual.
The song of a Siren could take the tiniest bit of curiosity from sailors on a passing ship and multiply it so that the sailors could think of nothing but reaching the source of the voice. The song of a Siren could find the smallest speck of fear - for who but fools are not afraid of something - and enlarge it so that the listener is overcome by it, unable to move, barely able to breathe. The song of a Siren could take a fleeting desire to end it all, and cause the victim to hurl themselves off of a cliff.
Lisanne wasn't about to reveal the full extent of her powers, but she had to do a few things to put her plan into fruition. The first time they took her in to meet the "sultan" she managed to deliver a few very quiet carefully-toned remarks that were perfectly normal greetings in word but caused the fat, balding man to drop to his knees in tears and beg her forgiveness for doing this horrible thing to her.
Word had gotten out all over the city of how their ruler had disgraced himself. Lisanne also made sure word got out through her handmaids that she was just staying in the palace for a couple of days to take advantage of the wonderful perfumed mineral baths. She really did want to take advantage of the spa treatments they were giving her (if she was going, to be dragged all that way, she may as well get something out of it) and her escape would be both easier for her and more defacing for Malivar if she laid low for a bit and gave them a false sense of security. She hoped the gossip would find its way to Alex and Daina and they would not worry about her.
"My Lady. The Sultan wishes to see you tonight. He has ordered that you be made ready for him."
"Very well. He shall get his wish." Her words and her smile were completely innocent. Her tone, to the women present, actually sounded somewhat apprehensive, but the eunuch backed out of the room uneasily and hurried away. She had been using that same tone with the eunuchs each time she spoke with them. She wanted to make them afraid, but not too afraid to function for now.
Kali had arrived at the city below the palace and so had the man who was shadowing her. Though he hadn't been able to follow her over the land, a few greased pockets gave him the destination of three women who had left the inn, and he managed to arrive a few hours before the carriage. His ship wasn't called the Silverwind for nothing.
He watched as the three companions made their way through the city, quietly gathering information. It wasn't difficult. Everyone enjoyed talking about the wannabe "sultan's" possible coming humiliation. He froze when a woman in leather approached them on the street and started talking. He wasn't supposed to make himself known unless absolutely necessary, but he couldn't hear a word of what she was saying.
