"Camp Grey is the contact point for all members of the Resistance working undercover. Mostly witches and wizards who still have steady jobs in the magical world and have not yet publicly committed themselves to the Resistance. It makes it easier for them to gather information and obtain equipment. I like to call them spies." He grins in amusement. "Camp White is more of a safehouse. There we harbour all those who cannot or do not want to fight, but still need our protection. They contribute in their own way. Research, logistics, brewing potions, refining wards – that kind of things. For example, half the Weasley family is there, as are the captives. Is that enough of an answer for you?"
