The Forgotten Realms [Fan Version]

The Grand Abyss, also known as the Blood Rift, is a bottomless chasm within the Infinite Layers of the Abyss, a scar that pierces countless layers via shifting portals. This perilous rift, devoid of a singular ruler, is a chaotic battleground where demons clash and corpses plummet into the toxic Blood River that snakes along its walls. The immense 21-mile-tall tower of Khin-Oin, realm of Phraxas, anchors itself within, its majority embedded in the chasm's walls. Ancient, precarious bridges span the depths, connecting portals at similar heights, guarded by wandering klurichirs. The red mist rising from the river fosters a sickly growth of moss and lichen along the canyon's ever-changing walls. Sages debate its origin, some attributing it to obyrith explorations, others to a cataclysmic clash between Demogorgon and Obox-ob. Navigating this realm is a fool's errand, as maps are rendered useless by the constant flux of its terrain and portals.

A vast, gaping chasm filled with swirling red mist and the echoes of distant battles, with the towering structure of Khin-Oin looming ominously above. The walls are slick with a dark, viscous substance, and the air is thick with the stench of decay and sulfur.
