Chronon Sea
From Jenny Everywhere Wiki
The Chronon Sea was the colloquial name of a “poorly-understood ‘layer’ of time” on a Multiversal scale, which was sailed by tachyonic sailing ships. The Sea was connected to the timestreams of all universes containing a form of time. (PROSE: The Winter Quests)
Lord Thymon took Jenny Everywhere on a “scenic jaunt along the shore of the Chronon Sea” on their seventh date. (PROSE: Family Business)
