Captain Henry Donnager expected a quiet career babysitting a dusty relic in Area 51. But when a test unlocks a portal to a world of knights and magic, he's thrust into command of Alpha Team, an elite unit tasked with exploration.

They join the local Adventurers Guild, seeking to unravel the secrets of this fantastical realm and the ancient gateway's creators. As their quests reveal the potent forces of magic, they inadvertently entangle in the volatile politics between local rivalling factions.

With American technology and ancient secrets in the balance, Henry's team navigates alliances and hostilities, enlisting local legends and air support in their quest. In a land where dragons loom, they discover that modern warfare's might—Hellfire missiles included—holds its own brand of magic.
