The scry cuts out. She stares at her blank scrying mirror for a few seconds.
The ship left between eight and fifteen hours ago. That is close enough to catch, perhaps, if a fast enough method of transit can be found. It may very well not be close enough to catch in the morning, if the destination is Ostenso. Ostenso is not so very far away. Four days, maybe. Could be five. That doesn't leave very much time to catch up, and the distance she would have to make up is increasing every minute.
She needs a sending. Two sendings. Needs to get the rest of the group together. Needs to think, needs to come up with a method that might work, the priests of Nethys will not respect her enough to help if she can't even demonstrate having thoughts. She will need to buy a scroll of teleport. The hard part is going to be getting close enough to Élie to teleport him back to Sothis. She can't just teleport onto the ship, because it's moving, and there is a very great chance that the spell will simply fail, even if she's scrying the place she wants to go at the same time. She will have to find another way.
She could try to talk some dolphins into catching up to the ship, and then tell the dolphins to stop just ahead, and scry one of the dolphins, and teleport to the dolphins, at which point she can turn into a dragonfly and fly to where Élie is. - this is not going to work, because even if she could convince dolphins to help her, and even if they were fast enough, they wouldn't know what direction to go in; dolphins don't understand human things like which of the many settlements on the Inner Sea she means when she talks about Ostenso. It might not even be Ostenso, and if she gets stuck in the middle of the ocean with no ship to catch, then she and Élie are dead, and that's no help to anyone at all.
She could buy a cloak of the manta ray, if one exists in this city, although she'd probably have to pawn her headband for a heartbreaking price to make it work, especially if the Church of Abadar won't let her take that much out of her accounts without Shawil, and especially if they refuse to do business with her at night. She has no idea whether manta rays are faster than dolphins (perhaps she could catch up if she didn't sleep? but ships don't sleep, it's still a question of relative speeds - ), and also no idea why she would think herself better at directions than the dolphins would be. If she ends up off course by even a little bit, then she might not be able to find the ship before it reaches Cheliax, and then what is she going to do -
She might be able to scry Felix. It is possible that Felix followed - he certainly didn't come get her, although of course it's also possible that Felix did not escape at all and is now dead - and it is possible that he can be communicated with, and it is possible that he can be convinced to stand still long enough for her to teleport to him, although Felix is not a water bird and she's not even sure if he can rest on the surface of the water like a duck. Maybe he would immediately drown, and you can't scry a drowned bird, now, can you.
She wonders whether that's enough ideas to demonstrate to a priest of Nethys that she isn't a complete idiot.
She could ask Nefreti Clepati for input. Nefreti Clepati is very old and very powerful and presumably very busy, but people say that she knows almost everything, and there can't be very much harm in asking, can there, it's not like 'I'm trying to keep my adventuring companion from unjustly going to Hell via Chelish execution' is a laughably petty reason -
She considers whether she should change clothes first, and ultimately decides that it is more respectful to break the law openly, because you think that you have a very good reason, than to break the law in a way that suggests you think yourself clever enough to get away with it. (The clerics of Nethys are, in any case, presumably somewhat less likely to immediately hand her over to the authorities than the clerics of Abadar would be, at least as long as she can demonstrate that she has a difficult problem to solve and is looking to solve it with creative application of magic.) She finds a closet and changes back into her own clothes, then circles around to the other side of the temple to ask for help, in case any of the wizards on the first side immediately recognize and report her.
She would like to know whether anybody here has two sendings left, and also whether it is true that Nefreti Clepati knows almost everything, and if so, how much it costs to have two minutes of her time within the next hour.
