"The Incunabula Vault is located at 23.0S 60.0E To reach it take the San-Chin Settlement Portal in Hebian-To at 41.5S, 82.1E. " This had me running for a lot longer than I needed to. A quicker rout is Sawato Portal [75.8S, 83.1E] >> Sawato to Mire Hill Portal [27.2S, 59.9E] >> End Point [23.0S, 60.0E]
