Scroll of Communication
This scroll actually consists of two scrolls, one wrapped inside the other. They are easily separated. If a message is written on one scroll, it immediately appears on the other. There is no limit to the range, as long as both scrolls are on the same plane of existence. The message may be up to 100 words in length. If one message is erased, the other disappears as well. Each must be erased before another can be written, and there is a 5% chance that erasing destroys the magic of both scrolls.
