You could be a long lost colonisation mission, refugees, a migratory species, etc. But if you have access to the technological and resource base of the "parent" civilisation, you'll be completely unbalanced.

Then there really isn't an issue then.
The colonies will send resources using robots & A.I. To help sustain the "parent" civilization, but the colonies themselves won't have access to the resource base of the "parent" civilization..

The colonies will also have to have to fend for themselves, even in times of war because of the sheer distance between galaxies. If the colonies go to war with another civilization, help won't arrive for hundreds of human years, and by then it may already be too late. So they are essentially cut off.
