The fire Kingdom was on their way to meet up with the Air kingdom on their way to the dark kingdom,their kings and enforcers onboard a small troop carrier

Fire Pilot:ETA ten minutes
Fire King nodded and looked at Dark Pyro and the other soldiers,
Dark Pyro:I and other soldiers shall escort you to the royal room when we arrive
Fire King:Very well...the Dark kingdom is unpredictable....we must be prepared

-Ten Minutes Later-
Pilot:Landing now
The king nodded and sat down,Dark Pyro walked up to the cockpit
They landed and the hatch opened,2 guards walked out first,then Dark Pyro,then the king,then 4 more guards,
Soon walked up to them
Soon:The king request your presence
Fire King:Very well

They followed Soon to the royal room,they walked in and saw the Dark king on his throne with he air king next to him

Dark King:You fire guards will stay
outside....the enforcer stays
The guards nodded and left the room,taking post outside it

Dark King:We wish for nothing but your help king Pyro
Fire king nodded and smiled gently
Fire King:We must accept due to our enemy's joining yours

Dark Pyro felt a weird sensation in him
Dark soldier over com to Soon:We are under attack!
Soon looked out a window and saw a small army of light,earth,and water troops nearing the base and bypassing most defenses,he jumped from the window with Dark Pyro behind him,they landed in front of the approaching army and all remaining defenses,holding up their weapons to fight,

The enforcer charged in and started to kill all of the troops of their enemy's,eventually soon took a wound to the leg but Dark Pyro saved him,after about 30-50 minutes the battle ended and all remaining light force troops were taken as prisoners or food for the brutes,
