Arrival

The name given to the event in which a Veil appears around a region in Mundana, and when the fog clears, the entire area has been drastically terraformed and one or more new races have suddenly appeared as well. The most common belief about how the Arrivals work is that Founder chooses a race to bring to Mundana and forms the Myst into a conduit that transports an entire region, with all of its geography and biology, from the original realm into Mundana.
