Around 8000 AC, orcs from somewhere west of Adellon began to settle Tavts. Ropog mythology says the Ropog taught the Tavti orcs to sail, but Tavti mythology claims the opposite. Either way, it is generally accepted that the orcish arrival in Adellon was not the calamity the Elven Invasions / Ishi Migrations / Adellonian Massacre was for the indigenous population.
