Httyd system in Westeros(Swapped)

**No Harem** *Expect quirky refrences and quotes* First off, english is my first language and also i just wanna make it clear that i do not own any of the characters or intellectual property excluding my main mc. All rights remain with their creators. So no infringement intended. * Pretty much a game like system novel, non sentient though. * Our mc gets a expedited trip through the afterlife after a chance encounter with truck-kun. After coming too, he discovers that he has been transmigrated to planetos, with a kickass dragon summoning/architecture system. Everything has a price in westeros. What will he do? | Im willing to take input along the way | Enjoy
