Silverwood Realm, Forest of Nature.
On a scorched plain just outside the forest's edge stood a menacing black tower, six stories of jagged obsidian that seemed to claw at the sky. Gates opened on all four sides, each one a gaping maw disgorging an endless stream of demonic monsters. Like beasts unleashed from their chains, they swarmed into the forest, drawn to the rich scent of life within the gathering places of other creatures.
In their place, a returning tide of demonic monsters flowed back into the tower, some hauling resources, others herding slaves, their bodies already twisting and corrupting from demonic influence.
The sheer number of demonic monsters suggested the tower's interior was a world of its own.
Within a vast chamber on the fourth floor was an unholy sanctum, a desecrated chapel to forgotten gods. There were no candles; the grand altar and surrounding effigies were all shrouded in an oppressive, impenetrable darkness.
