The Universal Constructors are a race of artificial lifeforms that exist in the year 1892 in the Universal Constructor Timeline. They have pyramidal forms, but their size and shape varies, as they are made up entirely of nanobots. They are an extremely intelligent form of life, and have a sophistocated, internet-like system of communication, that is difficult to interpret to traditional humans. Nebogipfel, a Morlock, sacrificed one of his eyes to gain access to their network. (The Time Ships)
