Magic Storage Encryption is the magical equivalent of file encryption, and in fact predates it by several millennia. Magic storage encryption by default limits the use of a magic scroll to only the one who created it. In order to create the alternative, an unencrypted scroll, one must employ some method of isolation of the scroll from one's own thoughts while creating it. One commonly employed method is the use of vimancy to create a spell scroll by moving a pen or stylus remotely. In essence this causes the potentia itself to be regarded by the scroll as its author, which has the effect of allowing anyone to trigger the scroll using solely the potentia contained within itself.
