Creating The Past

"'An establishment like this is a sort of verbal bulletin board, you know, and not only for Buddhists.'
"Right. That's why the Patrol quietly helped found it, half a century ago. In medieval Europe we do the same for certain monasteries." (The Shield Of Time, p. 56)

So how much of its own past does the Time Patrol create? Because of the Patrol:

Cyrus the Great was not murdered in infancy;
the Mongols did not invade North America;
Veleda became a pagan prophetess ("'The future was creating the past.'" Time Patrol, p. 633);
Red Wolf's people did not settle in Beringia but moved on to a "new world" further south;
the Knights Templar fleet escaped when the Order was suppressed.

There may be other examples in the texts and we can be sure that there are more in Patrol archives. Also, some of these examples are crucial for the entire future.
