Phoenix Logs/The Ark/The Foundry


 * The Foundry is a massive circular machine situated at the epicenter of the Ark
 * for the purpose of constructing and repairing the ringworlds that make up the
 * Halo Array.


 * Within its center it holds a mineral-rich moon in a powerful gravitational field
 * that is mined for resources by giant Retriever Sentinels, then used by
 * Assembler Sentinels to build components of a Halo. The Halo Array is always
 * made of seven ringworlds and should one be destroyed the Ark starts building
 * a replacement.


 * Once a Halo is stable, it is released to the same location as the destroyed Halo
 * to replace it while Sentinels continue to work on it. Of the seven ringworlds
 * that make up the Halo Array, six have originated on the Ark, while the seventh
 * was constructed on an earlier version of the Ark and later reconstructed to fit
 * the new design.
