In the depths of the Wargrounds sits a small home. On one side, constant sandstorms barred any passage in. On the other side blood rains on the ground. The skies run white with rotting and withered skulls flowing into upside down waterfalls flowing through portals in the sky. Some days, the world around is covered in a dense inky mist. Others, the horrors of the Wargrounds are clear to everyone inside.
And yet, this home sat in a place of perfect tranquillity. A place that refuses to age, and refuses to change. A place where the normal laws of the world apply inside a chaotic mess of spacial matter. The Grass was green, a clear waterfall flowed in a gentle curve creating a clear freshwater river, and food grew on a few plentiful trees. In here, the chaos around could be ignored as if the Great Calamity had never happened and nothing had aged.
People enter the Wargrounds for many reasons. Some enter for power, others enter to study the ancient history inside. However, some enter because they have nowhere left to go. They wander the Wargrounds in search of Salvation, hoping to avoid the monsters and Chaos within. When those people are near their end, a piece of string may manifest, guiding those in desperation to the Bastion. Their wounds are tended to, their supplies restocked and their stories shared. Upon recovery, they are spirited to the edge of the Wargrounds and their strings reclaimed. With it, their memories of this place vanish, never to be found again.
However, a noble few have stayed, guided by visions to help those in need. They meet the desperate, heal the weary and listen to the stories. They feed the hungry and take them where they need to go, because they have been in that situation themselves. And now as more and more enter the Wargrounds and battles surge, those few gathered and joined the Battle to protect their home, and the shelter it provides.
