Nymphs are beautiful creatures which looks exactly as someone wants them to look. They are a mirror of someone's needs and deeds. They are known to appear in the clear water of the @Riverlake north of Biforst. They make fun of seducing people coming by, but they don't do them any harm, except that time flows by in a different way. When in @Loos, the time outside walks by faster. It's common that someone appears years later after just a few minutes in Loos.
The Nymphs know about that, but for them time is a construct they don't know, since they are not touched by it.
