Sure! ^^ Probably doesn't sound that impressive or thought-provoking to you, and it doesn't have something to do with Vietnamese people/culture either but...

They are sisters who live in a small peaceful village, away from the war and chaos that's going on between the two major kingdoms, hidden behind a deep forest on a high land where the day is warm and the night is so cold, hence their clothing. But, with the chaos spreading across the land, the village's chiefs are getting worried that it'll eventually reach their village. Until these two sisters found these mechs in an ancient ruin and accidentally re-activated them. For some reason, the mechs aren't hostile towards them and the villagers. In fact, they are very friendly. The village's old and only oracle notices the markings on the mechs, and says these mechs have something to do with their ancestors, their ancestry line, the conflict, the power to 'control the mountain and the forest', the land itself, and the miracle that saved them in the past. When asked if there's more of these mechs, the oracle's eyes start glowing and she mutters incomprehensible languages before fainting. She told the chiefs to go 'look for the sign on the trees', and 'hear the calling through the rocks' if they want to save themselves. When some of them try to look into the ancient monolithic ruin that the girls explored, they found nothing but a couple of old children toys, which only add to the mystery.

...something like that. .-.
