- The Hadean (IPA: /heɪˈdiːən, ˈheɪdiən/ hay-DEE-ən, HAY-dee-ən) is the first and oldest of the four known geologic eons of Earth’s history. The Hadean eon started with the planet’s formation about 4.54 Bya, now defined as (4567.30 ± 0.16) Mya set by the age of the oldest solid material in the Solar System found in some meteorites about 4.567 billion years old. The proposed interplanetary collision that created the Moon occurred early in this eon, and the Late Heavy Bombardment is hypothesized to have occurred at the end of the eon. The Hadean ended 4.031 billion years ago, and was succeeded by the Archean eon.

A city situated on the eastern bank of Puget Sound in the state of Washington, and its surrounding metro area. Named for a 19th century Duwamish tribal chief from the region, who did not give an environmental speech often attributed to him. Home base of (or at least origin-point for) Microsoft, Nintendo of America, Starbucks, Boeing, Amazon and several other companies of note, and the birthplace of Grunge music (Nirvana in particular, despite not being from here). Its landmarks include Pike Place Market, Pioneer Square (which pre-gentrification was the original Skid Row), The Experience Music Project, a half-mile Monorail constructed for the 1962 World’s Fair which exemplifies Zeerust to a tee, the Seattle Underground which was a partial inspiration for Ankh-Morpork, and the Space Needle, also constructed for the World’s Fair.
