History & Background (Dossier)

• Note-1: Since the GURPS Traveller Universe doesn't diverge from the OTU until a short time before 1116, anything published for GURPS Traveller that applies to events earlier than 1116 or so also applies to the OTU.
• Note-2: The first few original LBB Traveller books did not yet have a developed OTU and were a generic RPG system, meant to be used as a template for other sci-fi backgrounds. The OTU developed later and became the default setting.
• Note-3: The New Era: 1248 diverges from the OTU due to the retconned explanation of the Wave. To what degree this divergence can be mitigated is yet undetermined.
