Silver Dragon (Patreon)

So the heist is on... neither side had it all their own way with both sides ending in a tie. The dragon guard in their last strong hold, the primary treasury, with most of the runners behind them. Long fang trading blows with forearm. The doors webbed shut and the only way out via portals controlled by the heist team.

But at the last second a thunderous roar sounded... crashing through the ceiling of the treasury, a silver dragon arrives surly lady Argenti. Her dragon guard start to rally as Long fang tells them to stand back.

Long fang with a booming voice that cuts through the sounds of battle yells... "that's not the lady" 

Suddenly, everyone realizes the danger they are in. As this dragon breathes, a stream of deadly cold.  This catches the portal mage as well as a number of others off guard. Trapping everyone. 

Another silver dragon has arrived to claim this hoard, and with no means of escape can you and your party take on this mighty foe?
