Location from Bastion by Phil Tucker
A significant location in Hell's depths — the setting of Book 3, where the Iron Tyrant rules and Scorio confronts the limits of his dragon form.
LastRock is where the series shifts from survival to conquest. Scorio doesn't just pass through this territory — he claims it, establishing himself as Lord of Nagaran and Master of the Black Tower. The location represents his evolution from refugee to power in his own right. The name itself suggests finality — the last solid ground before something worse. Whether that something worse is the Pit or something the series hasn't yet revealed, LastRock functions as a boundary marker between the Hell humanity can survive in and the Hell that exists to consume everything.
Deep Hell geography: heavier mana, darker light, landscape shaped by the Iron Tyrant's domain. Rock and metal merge in formations that feel manufactured by something inhuman. The deeper regions of Acherzua have a geological intentionality that the surface lacks.
