Izolda has offered her services as a laundress. She seems to have an inflated idea of the lifestyle lived by the magi at Schwartzburg as she envisions cleaning silks and satins, but it's true that with all those new uniforms someone will need to put some effort into keeping them clean. (Probably one or more of the crusader auxiliaries has been handling that, but they are experienced enough that they can no doubt find better uses for their time.) When she doesn't have washing to do, she can help as a maid in the castle.
Izolda is 18 and is a native of Cottbus. She is likely to be slightly disappointed by how mundane her life will be at the covenant (and tends to complain), but the masculine attention she will almost certainly receive will probably make up for it.
