Angelwatch is the largest tower in The City. It is in the Hammers district, and can be seen from most places in The City. It is a large, half stone, half iron skyscraper reaching around 100 stories tall. It is in the shape of a large hammer, and features a massive angel sculpture that is around 10 stories tall perched at the top of the tower. The tower itself is the headquarters of the Hammerites and is a testament to the glory of the Master Builder.
Construction of the building was finished around 40 years ago, and was the brain child of many of the Mechanist architects who ended up leaving the Hammerite order. Many Mechanists (including Karras) consider the tower to rightfully belong to the Mechanist order.
