Telmun (pronounced tel-MOON) is a small city in Talmithe under the control of Great House Hathna. Though located on the shores of the island of Larthial, Telmun is not actually inhabited primarily by Hathnan elves but rather by members of their subject tribes.
The settlement sits roughly a hundred meters out in the shallow waters of the Tabaha Bay, its homes and other buildings sitting atop a network of pillars that rise up to thirty feet above the waves. Its population are largely the descendants of Oscan settlers who arrived several centuries ago - these new arrivals were permitted to land on Larthial but not to live upon it, and so constructed their abodes out at sea, though they still return to land daily to farm and so forth.
The rise of the undead in Oscan lead to a small swell in size of Telmun, with roughly a quarter of its current residents originally hailing from Port Anzu or Velcitna.
