Sota, as well as his daughter Horiana, are the protectors, keepers, and gatherers of the clan's treasure, including any item of any sort made of gold.
Sota is a kind, wise old dragon, despite his tendency to be a bit greedy. Though only when it comes to gold. There are only a few dragons among the clan he can provide gold to without hesitation, one of them being the Queen, of course.
In short, he's basically the clan's banker / accountant. Using scrolls, he keeps track of who takes out treasure to spend, who might bring in stray treasure they've found, and how much treasure they have in the form of large estimations.

Within the clan, he often keeps to himself and spoils his beloved daughter with treasures and apparel that's of or is the color of gold. He tries to spoil his mate, but she always denies his gift, trying to show him that the greatest gifts are not materialized.
