Shoryaven came from the northern steppe cultures — Slavic-adjacent human stock, clan-organized, with a long oral tradition of genealogies and conquest narratives that he eventually committed to writing during the Great Expansion's prosperous middle centuries. He wrote primarily in the Common Tongue rather than his clan dialect, a deliberate choice that he described as making history "legible to the world it belongs to." His Chronicle of the Great Expansion runs to fourteen volumes and covers the Frost Fall, the Return of Dragons, and the consolidation of the modern polities in exhaustive and occasionally exhausting detail. The Return of Dragons is the spine of the work; he gives more of the fourteen volumes to it than to any other upheaval of the age, and reads the rebuilt peoples' war against the returnees as the hinge on which human dominion turned.
Shoryaven's cultural bias is triumphalist in the fullest sense. He worships Bylzar (the daemon of propagation, continuity, and gold) and he reads that daemon's domains as a lens for all of history: the world has been continuously propagating, continuously expanding, continuously accumulating. The Great Expansion is not an event in history; it is history's destination. This framing leads him to undervalue the pre-Expansion record. He cites Temavori as "elegiac and therefore unreliable," dismisses Erindath as "a Craggus-cult ledger-keeper," and describes Oblexan's fieldwork as "the archaeology of irrelevance." His treatment of elder-race accounts (elf, dwarf, orc) as inferior to human-authored records is consistent and unselfconscious.
His era is the Great Expansion and its immediate predecessors: the Frost Fall's disruption and recovery, the Return of Dragons as a political crisis rather than a cosmological one, and the formation of the polities that make up the modern world. He is indispensable for this period and untrustworthy on everything before it.
