1. No events prior to someone time traveling, may ever be altered. Their life prior to their first travel is untouchable by time shenanigans.

2. The past of a single branch may never be changed. Changing it would create a new branch.

3. The Imaginary Root will never occur as a branch or in the trunk.

4. No branch may expand infinitely.

5. No time traveling to a point before the beginning of the trunk of the tree of time (above ground part).

6. No time sprites shall appear or interact where two or more time travelers gather.

7. No non-time-based being may be employed by more than one sprite tribe.

8. Time sprites must abide their internal code, set by Corona. Breaking it results in erasure.
