Blitz - Age Chart

Infant: Blitz Stillsky was usually more quiet then most foals his age. His parents, Mirror Rose and Silent Swift, his mother and father respectively, were glad to see their first born to be well behaved. His sister was another case entirely...

6-9 (90 approx years since Luna's exile): Wanting to follow in his father's footsteps as a knight, Blitz was sent to be tutored as a page under a close family friend. While he did most of the usual work, he also practiced play instruments, particularly the violin and cello, which his earth pony mother was famous for playing.

10-19 (80 approx years since Luna's exile): At 13, he became a squire to the knight he worked under, and went into full training. He stood out mostly for his spear work, his father's preferred style of fighting. He detested armouring or wearing armour, and was more of a scholar and thinker rather then a fighter, but he always enjoyed sparring with his peers, which he wasn't the best at.

At 19, he was allowed to become a knight, a proud moment for him that he sure his family was proud of too. However, he received news that his family home was attacked, and his parents and sister had gone missing. Not much was known of how it all happened, except that it was a deliberate attack by other ponies. He left before his knighting ceremony could happen, and went searching for some clue to his family.

28-32 (70-60 approx years since Luna's exile): Spending nine years looking for something about his family, after dead-end after dead-end, he subsided into despair, alcoholism and guilt. He became aggressive to everyone after drinking, and became a mercenary out of desperation and callous for others.

At 32, he was hired to hunt down a rogue knight, hiding in a cave mouth. Having became apathetic to most at that point, he took the job without much hesitation. Upon arriving at the knight’s hideout, he quickly found the criminal, and engaged in battle. However, his drunken haze caught up to him, and he slipped up. The knight got a clean stab with his spear, right by Blitz’s heart, twisting it to do serious damage. He was on the brink of death, were it not for another stallion that had followed him, and quickly stopped the rogue knight from killing Blitz. He introduced himself as an old friend, named Nazaam, a vampire. He told the dying Blitz that there was a lot he had missed, and that he wasn’t done in his search. Nazaam revived him, using his own transfused blood to heal him...

32-50 (50 approx years since Luna's exile): The new blood caused Blitz to contract chimerism, causing heterochromia in his right eye, as well as making him a half-blooded vampire. It also caused long life and increased healing. His aging slowed, and has made him look in his 30's for years.

After hearing some explaination from Nazaam about his family, he decided to head home, finding it renovated and under the care of those that his father had served under. He spent most of his days inside, reading up on the extensive library to learn about the clues that Nazaam had given him. He eventually went back to travelling, moving from city to town to village, finally stopping in the same town that was built on the foundations of his old home.

75 and Up (Just before Season 1 and on): Not having much story to be told here, Blitz turned his life around. He settled down in the town, finding a nice place and starting up a hunters' group to feel the rush of a spar with another. He keeps his heterochromia hidden for the most part under an eye-patch.
He started to care for others, and regained his upbeat personality from years gone by. He soon started to date again, and gained some friends. He also fell for a unicorn mare, and married her years later, having two children with her.

HOLY POOP! This took forever to do... But it was pretty fun.
The idea was inspired by and and their characters. Go check them out if you aren't (But I doubt you aren't. They are great artist, better than I).

Also, he doesn't live anywhere close to the canon Ponyville or anything. I just use the times to give a basic idea.)
