Sure, Layna could lead the group to River Forge, but getting the information about the West Merui Company would be another story. She was sure Astaban and Karn would figure out something, but she hadn't put up with Talia this long to leave her behind if she could avoid it. From the far side of the river Layna calls loudly, "Up to you. You could try upstream or downstream some, if you'd rather swim."
You know, Layna thought as she sat on her horse waiting for the rest of the group to cross the river, a bit of rope and we could tie Talia to her horse and be in River Forge in no time.
