Lord Viserys was the head of the Grahmin Clan. Before the incident of the sacred temple, it was an ally of the Aurora clan. Although as an ally of a clan whose reputation was very poor, the Grahmin clan was known on the third and second floor as a down-to-earth clan.
All the members of this clan were very humble people. They would always uphold justice and they would not hesitate to punish their own clan members if they commit some heinous crimes. That is why in public opinion this clan was very popular. This clan was very strong and its strength could be compared to that of the Aurora clan. But despite that, they managed to become a good clan. And that was all because of the Lord Viserys.
