After some time in silent contemplation, Nero finally spoke.
"You said most humans can only survive bonding with one Seal. What happens if someone tries to take more than one?"
Lyon's smile returned, and this time it carried a hint of amusement and something darker.
"That sounds rather greedy, Nero." He said with a chuckle.
Then Lyon paused for a bit as though considering his answer.
"They die," he eventually said simply. "Or worse, they become something strange, like an abominable fusion of multiple corruptions that tears itself apart from within. The human soul is not meant to bear more than one Seal, you see. Attempting to do so is beyond even madness."
He paused, then added, "Though there have been... exceptions. Rare cases where individuals with extraordinary resilience or unique circumstances have managed to bear multiple Seals without immediate destruction. But these are anomalies, aberrations that I dare not speak of casually. The walls have ears, after all."
