This one's for the Fire Nation. Pretty self-explanatory, I think. the orange background represents their color, and the fire represents both their name and how their stings hurt like nothing else can.
If the Dark Knights end up splitting in two, the following two flags should be used for the North and South Colonies, respectively. The broken halves of the sword represent their shattered unity and the possible conflicts that might end up following. The black background represents the color of the ants in all three flags that follow.
The North gets the handle half because that part ended up being the upper half, and them holding the upper floor of your apartment.
Same reasoning for the South, but with the tip being the lower half and them holding the lower floor of your apartment.
This flag gets used for the Dark Knights if they don't split up.
The green wreath represents peace and unity between the north and south, while the white sword represents the fact that they can defend themselves if they need to.
Last but not least, the Golden Empire. The Golden Shield split into eight parts represents the eight queens of the colony and how they worked together with each other and with you to defend against the mite infestation, while the blue background is simply there to make the main focus of the flag really pop.
