[starwars] If there can only be one sith master and his apprentice then how can the sith order grow?

I was wondering this after playing some SWTOR because if the sith's rule of 2 doesnt allow the order to expand then how can the sith order grow? It seems to me that the rule is bound to make the sith order contract and eventually dissolve into nothing if enough sith are killed off overtime due to wars and "accidents".

The Sith Order is not meant to grow, at least not at first.  Its membership is meant to stay stable at two, and no more.  This is to help keep them hidden from the Jedi, and to help ensure the Sith Lords would grow stronger.  By having each apprentice defeat his or her master and repeating the cycle, the Sith philosophy would (ideally speaking) ensure that the Sith are constantly improving themselves and growing stronger with each generation.  And then, when the time comes that the Sith Lords have grown powerful enough to emerge from hiding and destroy the Jedi, then they would do so, and the Rule of Two would no longer be necessary.
