In the library of all knowledge

Ryan looked at his new pair of cufflinks.

It was the same pair of cufflinks he got immediately after beating up more than half of the first-year students.

It had been upgraded from 9-ct yellow gold to palladium-made cufflinks.

In this academy, the ranking system was based on these cufflinks, as they go from:

Plain copper for commoners.

Indium for fallen nobility.

Steel for baron-ranked children.

Regular silver for commoners with high-level potential.

Rose gold for count-ranked children.

Yellow gold for merchants and rich kids.

White gold for a Marquess or a Marchioness child.

Platinum for the future successor of a dukedom.

Sterling silver for the princess' fiance.

Rhodium is solely reserved for the prince and the princess.
