The massive assassination incident in the Royal Capital ten years ago, Shane had lost count of how many times he'd heard about it from others.
It was during this incident that Laischa came to the Human Realm, arrived at the Royal Capital, encountered the Demon King's remains as if it were destined, and took them out of the Royal Palace, creating Lasha.
It was during this incident that Tielle's mother betrayed the Kingdom, betrayed the Elbein Family, and was personally slain by Aridia, planting the seed for Tielle's later departure from the Elbein Family and eventually from the Royal Capital.
Many noble families suffered heavy losses during that incident, either losing important descendants or having their family heads assassinated.
At that time, assassins rampantly carried out massacres in the streets, turning the Royal Capital into rivers of blood.
To Shane, this was just something he heard from others, and as an observer and outsider, he had almost no feelings about it.
