Visitors
Aliens who visited Issenda hundreds of thousands of years ago during The Visitation, probably somewhere in the time period the Ancients would have dated 2004 to 2025 on the Gregorian calendar. The number of sages who hold to this theory is larger than one might surmise, perhaps because of the fair amount of certainty among scholars regarding the extrasolar origin of one other existing race not originating on Earth — the illithids.
Although both analog and digital records of the event may all now be lost to history, The Visitors were first encountered by human beings on November 14, 2004, during a U.S. naval training mission near San Diego. Two Super Hornet pilots were the first homo sapiens to observe this alien visitation.
This visitation was probably at least half a million years ago. The Visitors gave rise to various races and phenotypes, among them the Sarrukh, the yuan-ti, and true dragons such as Valashinaz.
