The massive sea-facing walls of Tâchumâz, known as Athena's Impregnable Bulwark, are virtually impregnable to sea attacks. First constructed by the Elderaunts of Ivory Asylum, they were later expanded upon by enslaved stone giants under Jairall Bloodtusk. These formidable walls extend into the city, becoming part of a vast network of walls, towers, and fortifications situated on hills, around villas, and protecting the estates of influential individuals.
