The Maris Stella's Eisen marines, Rickert, Geroldt, Aidel, Hartwin, Wolfram, and Franka, are ex-Roaring Drachen from Wische, pensioned off after various injuries. They are commanded by Johann Mueller. Constanza thinks of them as the "Sea Drachen." Or if you want the Eisen spelling, "Seedrachen."
They hired their services to Constanza after she found a way to rid Siegsburg of some of its predators in the adventure of The Ghouls of Siegsburg. What she didn't realize at the time was that they have also sworn to protect her, becoming her bodyguards.
[In game terms, the Sea Drachen are Rank 3 Eisen style brutes, meaning they take two hits to put down. (Uninjured Roaring Drachen would be Rank 4.)]
