History of Call of the Cryptolith

Call of the Cryptolith is a lore-collection triumph from Season of the Hunt: collect every page of the "Call of the Cryptolith" lore book.

How to complete

1. The book has eight sections. Per Destinypedia-style lore listing, entries are unlocked by completing that season's seasonal triumphs, so work through the Season of the Hunt triumph list; each completed one reveals a page.
2. When all pages are unlocked, the triumph completes automatically.
3. Note: the sources do not say which triumph unlocks which page, and the season is long past. Whether every seasonal triumph is still obtainable (or the pages have been unvaulted or retroactively granted) is unconfirmed.
