Trases was a large mining [article=Age] by 4330 DE. In [article=4334 DE|4334], Trases was "halfway destroyed" because of the mistake of a native running a D'ni machine. Families were forced to evacuate. In a strange case, a baby was supposedly born in the middle of a link from Trases to D'ni. This baby would eventually become known as [article=The Watcher], a prophet whose writings remained popular until [article=the fall of D'ni] in [article=9400 DE].
Detractors of [article=King Loshemanesh] used the disaster on Trases to prove the point that the D'ni should be cut off from other cultures.
