Defending against grey swords

This video explains what they grey swords mean and shows a scenario in which your guild can defend against that attack if it occurs on land adjacent to land your guild owns. You do not always want to defend grey swords. If the attacking guild is considered friendly or neutral you do not want to interfere but if an enemy guild setting the siege then you may wish to defend and even possibly steal the sector. Any guild member can defend without GvG permissions so make sure you know if your GvG leaders want you to be defending before doing so, make sure you know which guilds are friendly/neutral and which are not.
