(As a basic magic illusion,  her image is easy to erase for a sorceress,  but her presence goes where ever the doll is,  so without physically removing the doll from the ship,  you can't get rid of her, and since she's tethered to Valspan,  You have to get rid of Valspan to get rid of the doll.  Considering she was previously harassing Grandus, we'll assume her ability to stick to her preferred tether is above meli and whiska's ability to dispell on a local level. She's probably a bad example to start on since she's so locally contained, though they could probably learn loads from studying the doll itself,  since it's a super advanced containment device for the demon herself.  Not that Valspan will relinquish the doll.)<br/><br/>The girl frowned, her head slowly turning upside down until a deep, ripping, cracking sound could be heard, only stopping when her face was right side up.<br/><br/>In a voice that was decidedly 'unladylike' she replied with palpable spite,  "if I was free, there's no amount of your petty sorcery that could protect you from me." As if to accentuate her point,  the charms around whiska shrivelled and withered. The illusion disappeared like a puff of smoke, but the hate filled demonic presence only slowly receeded,  seeping back up through the floor boards back to her prison, the unassuming doll still in Valspan's grip.
