Stefan rushed out of the house and saw tens of Guards rushing towards the right wing or best described as the right walls. This piece of land carry no value, considering that the 230 Hectare new farm is in front of the Kingdom. It's just a flat land with the forest above its head.
It became easy to spot the approaching soldiers, on the walls a Guard shouted with a guess. "Enemies are 300 Meters away!" And his word was carried on all the way here for the rest of the Guards to hear.
This most definitely proves war, because they didn't send a messenger demanding any requests but charged right away. They are running with all their might towards the Kingdom, and furthermore King Michael wasn't informed of any Soldiers stopping by the Kingdom. They can't be any friendly Platoons and green skins are spreading all over the field.
Stefan ran back in and shouted. "We are being invaded, grab Misses Wood and lets go to the Castle!"
