Bell Tower

A bell to alert all the ratizens in the city. Might be stressful, but sometimes it is needed.
Overview
Bell Tower is a building used to gather nearby A_Ratizen to its location when it is rung. Its effect covers a radius of 19 tiles at base, up to 40 tiles when improved, and the gathering effect lasts for 2 hours.
It is mainly useful as an emergency response tool during raids or other dangerous situations, letting you quickly pull A_Ratizen away from exposed areas and concentrate them at a safer point. Because its effect is based on range, it works best when placed where important workers or residents are likely to be within reach.
