The Railway Engineer in “Runaway’s River” is very different from the Engineer of
“Runaway’s Railway”. She is, of course, a superb engineer (otherwise the Railway
would not have chosen her as an Avatar), but she is considered to be rather… alternative.
She has a tendency to make unusual engines that operate in unconventional ways, and
decorates them with Gothic embellishments. Not much is known about her past, but
it seems clear that she has survived in a war zone.
