Managed to get to one of the great filters at least.
Sruo
We first became aware of the Sruo in 4080. They reside on the misty planet Sruo in the Fro system. They are outgoing, passionate, and resilient.
The Sruo use stone tools in a variety of contexts, especially when hunting the wild u‑ofrëmuh.
The Sruo have begun to cultivate crops. They are especially fond of oso, a kind of fleshy cactus.
The Sruo have developed a simple system of writing, which they use primarily for storytelling.
The Sruo have begun to watch the skies and recognize patterns in the movements of stars, which they use to navigate over great distances and keep track of time.
The Sruo have begun to construct permanent dwellings and other structures. They make especially extensive use of the wood of the oso plant as a building material.
The Sruo have learned how to catch water-dwelling creatures such as the frëu, which is now a staple part of the Sruo diet.
In 4323, many of the fractious Sruo tribes were united under a single banner by an individual known as Fruë the Merciful. The city of Omo O‑ofromëh has been made the capital of the resulting empire, which rules over approximately 40% of the entire Sruo population. Unusually for the Sruo, it is governed by a council of clerics.
The Sruo have domesticated a species of small flying animals. The pets assist their Sruo owners with pest control in exchange for food and shelter.
The Sruo have mastered the control of fire. They use it to cook their food, and to light their villages at night.
The Sruo have developed a sophisticated understanding of basic mathematics, such as arithmetic, algebra, and geometry.
The Sruo have learned how to build ships and sail them across the oceans of Sruo to explore and trade over increasingly greater distances.
The Sruo have begun to make use of more sophisticated construction techniques, relying on sturdy structural elements such as arches and buttresses to support larger and larger buildings.
In 4480, the Sruo population reached 25 million individuals. Many of these live within permanent cities, the largest of which is known as Omo O‑ofromëh and has a population of 82,000.
The Sruo have discovered how to forge molten metal into jewelry, tools, weapons, and armor.
The Sruo have built elaborate pipe and sewer systems to supply their larger settlements, such as Omo O‑ofromëh, with fresh water and a hygenic means of waste disposal.
Following a long series of failed attempts to attack the city, Omo O‑ofromëh has become renowned among the Sruo as an impenetrable fortress. The image of its distinctive walls has been widely adopted in Sruo literature as a symbol of resilience.
The Sruo have begun to use lenses and mirrors made from polished crystal, glass, and water to redirect and focus light.
The Sruo have developed a simple printing press, and mass-produced versions of important texts have begun to circulate widely throughout the world. Scary stories are especially popular.
Some of the Sruo have begun to experiment with alchemy, systematically searching for new ways of combining and manipulating ingredients to yield useful chemicals, compounds, and medicines.
The Sruo have begun to construct wind and water mills, which redirect the forces of the natural world to perform repetitive mechanical tasks such as grinding grain and pumping water.
In their efforts to understand the motion of planets in the sky, free-falling bodies, and projectiles, the Sruo have developed a new branch of mathematics which is immediately recognizable as calculus.
Through systematic observation and categorization of the various living things on Sruo, the Sruo have begun to develop a more sophisticated understanding of biology. Some theorists have even put forth the idea that dramatically different-looking organisms, such as the u‑ofrëmuh and the frëu, may in fact share a single common ancestor.
In 4591, an emerging religion known as Frou was declared the official religion of the largest Sruo state. Adherents of Frou wear elaborately decorated fabrics to mark themselves as believers.
The initially controversial theory that diseases are caused by microorganisms has begun to catch on among the Sruo, leading to the widespread adoption of public health policies which have greatly reduced the spread of disease.
The Sruo have developed a practical and cost-effective steam engine, which can be fueled with wood or coal.
The Sruo have arrived at a sophisticated understanding of genetics, which has enabled them to craft new forms of life by deliberately modifying the genes of existing organisms.
The Sruo have successfully tamed electricity, and are now beginning to deploy it throughout society. Electric lights are widespread, electric motors are used to drive factories, and the growing need for electric power has led to the construction of power plants near every major center of Sruo population.
The Sruo have discovered a way to manufacture gunpowder, which they primarily use in warfare.
The Sruo have begun harnessing the power of electricity to send messages across very great distances with unprecedented speed. Due to the overhead of encoding and decoding messages, long-distance communication remains far from instantaneous, but it is now possible for individuals on opposite sides of Sruo to exchange several messages over the course of a single day.
The Sruo have developed flying machines which can carry them into the skies above Sruo.
The Sruo have begun to develop rockets.
The Sruo have developed an accurate model of the internal structure of the atom, which has also enabled them to understand the phenomenon of radioactivity.
In 4699, the Sruo successfully detonated their first prototype nuclear weapon. It remains unclear whether the Sruo scientists who worked on the bomb understand the sheer destructive potential of the weapon they have created.
The Sruo have discovered that electromagnetic waves may be used to transmit information, enabling the development and widespread deployment of media for audiovisual broadcasting.
In 4715, a single nuclear weapon was deployed in an attack on a medium-sized Sruo city. The incident did not escalate into a full-scale nuclear war, but the city was almost completely obliterated, resulting in the deaths of some 212,000 Sruo.
With the development of the transistor, the Sruo have begun to construct more sophisticated electronic circuits.
The Sruo have begun to build general-purpose programmable computers.
In 4736, an early warning system employed by one of the major Sruo superpowers detected an incoming nuclear attack. Whether the alert was a false alarm remains unclear, but the resulting nuclear counterattack and ensuing full-scale nuclear war has plunged Sruo into a state of nuclear winter from which it is unlikely that Sruo civilization will ever recover.
