The underground bunker

The eastern gate thundered under the relentless assault of the demon horde.

The gate was a massive bastion of reinforced steel and ancient enchantments.

It held a critical choke point in the kingdom's defenses.

If the gate fell, the demons would flood into the city like a tidal wave of darkness, cutting off supply lines and surrounding the palace within minutes.

Flaming projectiles soared through the air, smashing into the gatehouse towers.

The defenders atop the ramparts loosed arrows and hurled boiling oil, but it did no good.

For every demon that fell, two more took its place. They just kept multiplying.

From the clearing where I stood, I could see the battle unfolding.

Demons—hundreds of them—swarmed the gate like ravenous beasts.

Some scaled the walls with clawed limbs, while others hurled themselves against the reinforced doors.
