Ch. 341 Breakthroughs in alchemy

During one of the first of many trips to bring back his daughter Luna, Elric had a long talk with his grandfather Ker about the changes he made to the circle of runes gateways and the "Glass tablets". Ker thought that the current changes to the gateways were fine. They were still mostly secure, as one still needed to know the location name given to the node, and have origin blood, or a token that contained it. So unless someone had their blood or blessing to use the circle of runes gateway network, it was impossible for them to make use of. Ker suggested caution in making any more changes without fully grasping how they worked completely, after what would be years of study.

"I see so those glass tablets are more like books than pages. Beyond you and your daughter, who else knows about this discovery?"
