Day 4 - World Building Scars

The instructions: "Jot down some of the Really Big Land Features you want in your story and just think "what if that were made by...." Write down a couple of causes for those features and scars."

Heavy Magic:

1. The world is 1/4 the size of the Earth and 1/4th as old (about 1 billion years). The year is 400 days and the days are 24 hours long.
2. The three moons were made about 250 million years after the formation of the planet by an asteroid collision. The largest, furthest out is Yellow Moon, which orbits ten times a year. The next is the White Moon, which orbits once every ten days. The smallest and closest in is the Gray Moon, which orbits four times a day. The moons all align on the Spring Equinox so that's new years. There are ten months in a year and four 10 day weeks in each month. You can also tell time at night (or on certain clear days) by the Gray Moon.
3. Cenotes and circular craters were formed from asteroid and meteorite strikes. There was a great slew of them between 50 million years ago and 10 million years ago.
4. Aliens landed about 100,000 years ago. They colonized Brownland and brought with them many species that eventually became dominant over the natives. They genetically engineered the people of the Great Old Empire on Yellowland.
5. The Great Inland Ocean was formed when the mega volcano blew about 10,000 years ago. This destroyed the civilization of the aliens and buried it. Almost none of their artifacts have ever been found. Many of the people escaped, but a very few sailed east and west to establish themselves on Fjordland and Wispolill. None of those people have any memory of the original alien civilization.
6. About 100 years ago a broken comet struck and started an ice age[strikeout], and also released the energy that would end up being magic.[/strikeout] It caused the Great Old Empire to go into decline, especially on Yellowland (north). Before the ice age the polar caps only touched land in the winters.

Seekretya (the name of the country in the children's fantasy)

1. Seekretya was once a ley line nexus where powerful magic accumulated. When the scientific method was developed, about 1000 AD in the Muslim world, it started driving magic creatures, items and magic itself along the ley lines. As time went on Seekretya became the ultimate sinkhole for all things magical. The more modern society developed the more it drove things there. Specific events included:
2. 1492 - When the new world was discovered it forced all the magical animals into Seekretya.
3. About 1600 - Galileo's work forced all magical races into Seekretya
4. 1687 - Newton's Principia forced all magical items, the last of anything magical into Seekretya, which at that time became the last refuge of magic in this world.
5. 1880 - Tesla's work with electricity, and the spread of electricity, led to the collapse of Ley Lines. With the Ley Lines gone, no magic could ever get in or out of Seekretya by magical means.
6. 1950s - The use of atomic weapons super-charged the magical energy in Seekretya, giving it enough power to avoid detection, and travel by any means. This also prevents any electrical devices from operating correctly in, above or below Seekretya.
