Sbi story but easily adaptable
War has been raging on for years until one great day when the war finally ends. The 3 children of philza have been fighting since they were of age to be signe up. Much to philzas dismay and lack of wanting them to fight, Techno was desperate to fight for his land and with his fighting skills he was a recruited immediately, Tommy wanting to follow his older brother signed up aswell. They headed of together to battle. Wilbur stayed back not feeling the want for violence as much as his brothers, thst was untill he too was forced to sign up by new government laws.
When philza hears that war is finished he doesn't wait to get to the station to meet his kids once more. However as the last of the transport leaves his children are no where to be seen.
He was told they were alive, where were they?
After some research they find that there transport back from battle had been attacked killing everyone on board or so they thought thre survivors remained (techno, wilbur and tommy) and taken prisoners
At the camp they meet others (ike tubbo ranboo purpled....) who mse transport too had been captured
They have to try to escape and get back to philza whilst he trys to rescue them not believing they are dead
Obviously a lot of this can be adapted but the general plot is the idea for this story
