What is a group of Universes called?

A group of universes is commonly called a Wonder.

Collective nouns are fascinating linguistic constructs that creatively combine words to describe groups and gatherings of various entities. When delving into the realm of fictional or hypothetical universes, creative minds have contrived unique and captivating collective nouns to encompass the countless worlds and dimensions within these limitless domains. These collective nouns exemplify the imagination's boundless nature and aim to encapsulate the vastness, diversity, and sheer magnitude present in these parallel realities. Throughout the imaginative cosmos, collective nouns such as stellar clusters capture clusters of universes, resembling celestial formations strewn across infinite expanses of ether. The term cosmic amalgamation aptly denotes medleys of universes seamlessly interwoven, merging and diverging in an ever-evolving cosmic tapestry. As the expanse of the fictional exoplanets stretches forth, multiverse gatherings seem to emerge with "univalence"- an ensemble of isolated universes intertwining periodically, akin to ephemeral pieces of a vibrant collage flowing through space-time. Adjacent to the fleeting encounters of rippling timelines, "Interconnectorum" denotes borrowed realms binding together - a collective union of interconnected universes finely intertwined, their fabrics commingling across cosmic boundaries. Glittering clusters of proxy dimensions, known as the "Apexian Solidum," evocatively symbolize universes melding their essence at distinctive junctures deemed apexes, resulting in celestial displays that captivate cosmic onlookers. Precious leviathans refract universes within their luminescent hides - these remarkable beings who inhabit the spaces between dimensions are known as the "Nexusfins." These magnificent creatures traverse interdimensional barriers and possess interstitial universes seamlessly tucked beneath their ethereal fins, making them resonant guardians of both literal and metaphorical gateway realms. Enliven with metaphors and inspirational polysemy, these collective nouns endeavor to describe realms beyond mortal grasp. They awaken our shared longing to explore the impossible and ignite the fires of curiosity, translating limitless universal musings into words brimming with concepts and possibilities. These extraordinary collective nouns exist as linguistic keys soaring beyond mundane lexical barriers, unveiling the mystical vastness of multiversal landscapes that inhabit the realms of our collective imagination.
