Athenas Impregnable Bulwark, the sea-facing walls of Tâchumâz, are massive in size. First by the Elderaunts of Ivory Asylum, then added to by enslaved stone giants under Jairall Bloodtusk, they are virtually impregnable to sea attacks. The walls extend into the city, becoming part of a great network of walls and towers, on hills, around villas, and those protecting the estates of some important personage.
