Tayac is a system near Xi’An space that is best known as the location of the Ark orbital platform. Opened by the UEE in 2800, the Ark was built following the end of the cold war with the Xi’An and meant to be a repository for universal knowledge as well as a neutral ground for diplomatic discussions between species. Though it has been used infrequently for diplomatic purposes, the Ark’s massive library contains a wealth of invaluable historical information.
