Foundation Blocks are integrated into numerous realms and celestial bodies of the Mortal Systems. They come in a wide array of sizes, some as colossal as a mountain range, while others are small enough to serve as the foundation for a modest table. Their shapes are equally diverse, featuring intricate web-like grooves on spheres, blocks, mounds, or even an expansive latticework spanning miles. Scattered across entire worlds, buried deep underground, nestled within hills and mountains, at the bottom of gloomy bogs, or comprising the centerpiece of grand fortifications, these Foundation Blocks fortify worlds against the ravenous Chaos.
The latticework of entropic energy that binds Creation's spheres and orbs together remains an enigma, comprehended only by their creators. These Foundatin Blocks possess a tangible essence, akin to the force of gravity. They serve as steadfast shields, shielding us meager mortals from the tumultuous Sea of Entropy at our doorstep.

With a stone-like appearance and no discernible magical properties, most Foundation Blocks are challenging to locate. Some, such as Benevolence's Crown, are sizable regional landmarks. These areas can be quarried, but the stone gradually deteriorates over time. Conversely, the quarried sites undergo regeneration, eventually sealing the mined passages. Nonetheless, some incur significant costs to obtain the material, utilizing blocks to fortify an area against Entropic influences.
