Cargan wouldn't stop seething with anger at his brother. This confirmed all is his suspicions about him.
Indeed, Adramelech had found the cure and had been lying and deceiving them all.
If any of his brothers were to become the betrayer, Adramelech would be the last on his list. He was the oldest and also the most thoughtful one.
Adramelech was the brother who understood his duty as the first brother among seven and imposed upon himself that duty.
Even though he could be lazy most times, he was still there for them as the big brother they deserved.
Yet, he stabbed them all in the back. He watched them suffer for eighteen years while having a cure?
Even before Cyfrin announced the cure could only cure one of them.
However, from Cyfrin's message, Cargan thought the cure just only emerged and not for 18 years. Could there perhaps be a cure somewhere, one different from that aforementioned by Cyfrin?
Or was the heaven's message a lie?
