Interesting that Kesselbroods would want to marry into a none noble house. At least them being non-aristocrats seemed to be the main focus Isotope wanted to get across.

They're sortve de facto nobles though and they're rich and have control of manufacturing that the Kesselbroods lack. Good point though. If we develop the storyline at all the fact that the Sefts are technically not nobles should come up.
