As she crawled onwards with her heart thumping against her ribs like a caged wild hare in a frenzy, she thought about the last thoughts she had thought about the prince before finding out that he had been taken. She didn't know why, but she felt like that negativity was bad luck for them. Then, as even the ceiling got too low to be properly on all fours in the tunnel, she thought about Ligur and how horrified he must have felt. Of course, she didn't even know if he was still alive. That didn't make things any better.
She realized she was weeping again as she came to what could have been a concealed door. The only thing that was properly visible about it was a valve and the onslaught of rainwater pushing through the gaps. Otherwise it could hardly even be called a hatch.
