Peppermint uses these rocks to make the fire going. Since Hestia demanded that Peppermint must learn more about family, Peppermint asks every camper to use memory rocks so she can burn them into the fire like coal.

Other uses
The memory in these rocks can be shared with another person. (like how Hazel shares her black outs) All the user has to do, is to concentrate on the rock and slowly crush it in their hand.
