Alt. Rocks 2: Memory Quartz
Memory quartz is a magical mineral found on several Fantasy Earths. When treated with the right substances, it can be made to retain the memories of any one person. There are limits, of course, but as a rule of thumb, a piece of memory quartz the size of a deck of cards will hold six third level spells. The memories stored inside the quarts will remain there, pristine, until they are removed or the stone is destroyed. A piece of memory quartz the size of the one described above will sell for no less that 500 gold.
