The Far Realm contains horrors too unimaginable to comprehend. A mind might bend or break trying to make sense of these oddities. Creatures of the Far Realm tend to leave traces of their home scattered far and wide. The endless nature of the Far Realm comes in part from the seeds of madness planted in other planes, in the form of trinkets and tools. Tools which endlessly create copies of themselves, each time tearing open the fabric between worlds. Shells that invite a listen, only to fill the mind with a distracting and haunting song. The eyestalks of a beholder woven into a focus for magic, with unforeseen consequences in its use. Some few have fought against the Far Realm, creating tools that hold memories within them, so that travelers would not lose themselves on their journey. Of these few who rebelled, there was a traitor to Illithid and the Far Plane both, who created an item of incredible power using the twisted psionic powers afforded to him. This artifact was built not to destroy, but to protect those dearest to them.
