Terra

Summary
A relatively tranquil and peaceful mirror for the reality of Earth, Terra's timeline is a reflection of Earth's, though its history is far less bloody, its people happier and more prosperous, and its future far brighter. However, Terra lives in dread with the knowledge that its fate is tied to that of Earth, as the events of one usually mirror those of the other, and as the prospects of Earth grow ever-bleaker, the people of Terra prepare for the possibility some great calamity will befall them in kind.

On Seedorus
Terra remains largely unknown on Seedorus except among the most knowledgeable planeswalkers and students of the Multiverse. Aside from a few recorded encounters with Terra's Huems, very little is actually known about events on Terra.

Historical Overview and Timeline
To know the history of Earth is to largely know the history of Terra, and vice versa, but the two have diverged radically in recent centuries in some respects. While Terra's existence remains unknown to Earth, Terra has possessed limited knowledge of its dimensional twin for centuries and noticed patterns of correlation between the events in both, with a unique sort of symbiosis where parallel events tended to turn out with different results that nevertheless remained largely parallel thanks to other subtle influences.
