Buildings

A city has one of each of eight buildings, each from level 0 to 40. A city's Keep holds 4 levels of the other seven for each of its own levels, spent any way you like; the Keep itself rises freely. 3 upgrades may wait in a city's queue at once, and you pay for each when you order it. While you're protected, a city's first upgrades take 25 seconds. Where the resources go →

Every figure here is at a world's normal pace, speed 1. A faster world scales them: at speed 2 every time halves and every rate doubles.

Keep

The city itself: its size, its tax, and the room the other buildings rise in — four levels a Keep level, spent any way you like.
