Hero of Darkness

On the second day of training in Artificing, just like before, Throk started explaining the ins and outs of the craft to build Kahn and Blackwall's sturdy foundation and thus, he started with the advanced knowledge from the get-go after seeing how much potential both of them had displayed after receiving the enlightenment. 

He drew the sign of two overlapping circles curved and connected to each other. 

"Do you know what this sign represents?" he asked. 

"Infinity." replied Kahn the very next moment. 

"Hah? Did you read about it in the books?" 

"Ah… yes." replied the human disciple. 

Kahn was a man of science in his previous life. So he obviously recognized the infinity ( ∞ ) sign. 

"Let me ask you something. 

Imagine that this is a flow of mana and world energy represented through this sign. 

Can you tell me what principle this sign represents?" he asked in a serious voice. 

"Limitlessness." spoke Blackwall although he had no prior knowledge about this sign like Kahn. 

"What does this signify to you?" asked Throk to Kahn. 

"No true end, incalculable, something that is impossible to be quantified." he replied like the true nerd he was in past life as Elric. 

"Good. How would you two feel if I told you that we can apply the same principle while carving runes?" asked the old dwarf with a coy smile. 

To his statement… both the disciples had their eyes wide open. 

"Impossible! Mana and world energy don't work like that." spoke Blackwall. 

"Ha ha! Then tell me something… Where is the point of origin and where is the end. 

Also, which direction is it flowing in?" 

To his question… both Kahn and Blackwall were too stunned to speak. 

Because if this logic could be used in Rune carving… there were simply infinite possibilities. 

"Now do you understand how Runes can sustain and integrate themselves?" asked Throk as he tested the cleverness of his disciples. 

Both Kahn and Blackwall spoke in unison as they finally understood why Runes worked the way they did… they finally understood the very foundation of Runes and Artificing itself after coming to this mind-boggling realization. 

"Self-reforming, self-regenerating and most importantly… self-sustaining."
