It's true we have no reason to go out of our way to engage these contacts, and that they are to be repelled if they come near to the Naha, but if we have the upper hand and opportunity shows itself, we have to take it.
These Outcasts cannot be fooled into thinking they can station themselves in our space. The power of the GMG must be expressed here and now. As soon as these fools understand the concequences of their actions, our operations will be able to run much more smoothly.
This is not to say we shall seek out these trespassers. It is foolish to enter combat with such ones alone and out of the way, but if we have an advantage, we must take it.
