The year 35,453 before the Battle of Yavin (BBY), also known as 1,000 TYA, was a period of time in the pre-Republic era. Around that year, Osamael Or was recorded saying "There are depths" while describing the unexplored regions of Tython. Around that time, Or wrote The Gree, and Everything I Have Found of Them in the Old City as he explored the Old City, though he disappeared not long afterwards.
