We found this online:  “Fontaine: Dance of the Dew-White Springs (III) contains Achievements related to Fontaine and rewards the Fontaine: Redemption Namecard” and we have no idea at all if it relates to this set of 30+ unused and unopened cards, for which you might see our entry 40400080.  Sorry for the imprecision, but if you translate these titles and Google them with the extra words “Genshin Impact”, you will see what we mean.  Grade: 1.
