Herald of Mei Lung

The E'soa Ho-chi, also known as the Herald of Mei Lung or simply the Herald, was an artifact that took the form of a tome that told the whole history of the world—right up to the present moment. A creation of the great Dragon Lord Mei Lung and a vital instrument of the Celestial Empire, it was kept secure in the Ko'Chung Gompa in Tabot.

Description
The Herald was huge, about as big as a small shield and thick   and so heavy it took at least two men to lift. The covers were decorated with gold and pieces of jade of blue and green hues, of otherwise unremarkable appearance. Within, the pages were the thinnest possible paper and the text in an elaborate script written in golden ink. It was unreadable to anyone without a comprehend languages spell.

It was kept open at all times, with existing writing on the right-hand page and new writing appearing as one watched on the left-hand page. The page must be turned regularly to keep the magical writing flowing; anyone could do this.

Powers
The Herald of Mei Lung had the amazing ability to always and automatically record nothing less than the entirety of history, with every significant event and almost every minor event, in the past since the beginning of the world, to the present as events happened, and even beyond, in the future with events yet to take place. Its account was true and accurate, but frequently one-sided and focused on the history of Kara-Tur, with only occasional references to Faerûn if something interesting happened there. The book itself decided what was worth recording. The future, hidden away in the final pages, was still forming and fragmentary, as events were still coming together.

The person who turned the page with the still-writing text could focus the Herald 's account of current events to whoever, whatever, or wherever they were interested in. They could also look back and research past events, but given the sheer length and scope of the work, this was a time-consuming affair, taking up to a hundred days of reading to find something specific. They could also look ahead and research the future the same way, but had no guarantee of finding anything useful, let alone complete.

In case of theft, if the Herald was ever missing from the monastery for over twelve hours, a potent spell on it would automatically teleport it back.

History
At some point, Mei Lung gave the E'soa Ho-chi to the Ko'Chung lamas to preserve his chronicle of history should something terrible happen to him that even he did not foresee.

Background
The magical book called the E'soa Ho-chi or the Herald was first presented with a short description in Kara-Tur: The Eastern Realms Volume I (1987). It was later given a longer, setting-neutral write-up as the Herald of Mei Lung in Book of Artifacts (1993). When Encyclopaedia Magica Volume IV compiled magical books together, it presented both the E'soa Ho-chi and the Herald of Mei Lung as separate items, despite having similar powers, creators, stories, and names, and on the same page. This article merges the different accounts back into a single item, but the varying descriptions could suggest companion books.
