You bow deeply and produce a polished dragon-scale tablet from your satchel. 'With your permission, Exalted One, I shall manifest the possibilities.' As your fingers dance across the surface, the cavern fills with a dazzling holographic simulation. The very mountain trembles as the projection expands to fill the chamber, gold veins in the walls pulsing in sympathetic rhythm.

The visualization begins with Valthorix's current hoard - a literal mountain of coins and gems that stretches into the gloom. Then streams of gold peel away like living tendrils, transforming into miniature representations of possible investments. A river of molten gold becomes a chain of dwarven forges, each tiny anvil producing glowing ingots that multiply as they float upward. Rubies detach and blossom into floating vineyards where spectral elves tend grapes that drip liquid silver.

'Observe the compounding,' you murmur as entire new caverns begin forming beneath the projection. The Storm Giant investment manifests as crackling thunderclouds that rain platinum coins, each drop splitting into more coins as they fall. Most impressive is the Antiquities segment - Valthorix's actual treasures begin glowing where they sit, showing how their value could appreciate if professionally appraised and selectively sold.

The dragon's massive wings unfurl slightly as he watches his hoard potentially triple in size. 'This sorcery...' he rumbles, reaching out to bat at a passing cloudship made of solidified moonlight and numbers. 'You make wealth multiplication look like...' His eyes narrow suddenly. 'Wait. Where is the insurance against dragon slayers in this pretty illusion?'
