Greed
This scene was somewhat similar to how wealthy Middle Eastern individuals use golden trees to adorn the entrances of their hotels.
It also couldn't help but remind David of the words Tiamat had once said to him: "The plundered treasure is indeed Her power."
From this perspective, the Dragon Queen's power was comparable to mountains and seas.
In addition to Gold Coins and gems, the treasury also contained various Magical Items, including Magic Wands, Magic Swords, Armor, Magic Scrolls, and Magic Potions. These Magical Items were placed on specially made display stands and were being traded by Dragons as if they were mere commodities.
