“That’s an Ancient Long Range Communication Device. Stargate Command encountered them twenty years ago. They’re very tricky Sister. When used in conjunction with the communication stones they form a psychological link as well as a mental link with the users.”
“What do you mean?” Sister Helena asked.
“For example, if you and Maerwynn were linked with this device, if she was drowning in a river you'd feel the effects of her drowning. If she were to die, you’d die as well.”
Sister Helena shuddered. “Oh my!” She exclaimed.
“That’s not the worst part. There’s no “off” switch that we know of. The only way we’ve turned the device off is by disintegrating it.
“I see.”
“Did Maerwynn or her parents try to connect the stones to the device?” Larkin asked.
“Not to my knowledge,” Sister Helen replied. “They thought it was a GDO.”
