Ivan Wolff was dropped at the steps of an orphanage when he was no more than a couple hours old. Nobody knows who his parents are or how he wound up at the steps of an orphanage, he just did.
Growing up Ivan at the orphanage didn't seem to affect him all that much. Most people were surprised to learn that he was an orphan to begin with because he seemed entirely normal. Ivan, for the most, was a pretty unremarkable kid. He had a few close friends but they weren't like BFFs or anything, which is probably why nobody missed him when Ivan's very normal life went to hell.
Ivan was about eleven years old at the time, and he was going for a walk in the woods after school let out to clear his head. There this kid that liked to pick on Ivan because he was an orphan, his friends usually stuck up for him, but they were all sick today for whatever reason. Either way, Ivan was walking in the woods and he quickly lost track of time and before he knew it... the sun had set and the moon had risen. A gorgeous full moon, which lit up the forest like the sun was still out. Unfortunately for Ivan, this was the last full moon he'd be able to experience as a human.
Ivan had turned around and was walking back to the orphanage when he heard a low, ominous growling sound coming from the woods. Ivan whirled around trying to pinpoint the sound but was having no such luck, when Ivan's back was to whatever was growling at him... it pounced, knocking Ivan flat on his back and bit into his shoulder blade. Ivan screamed in pain, but the creature wouldn't let go... then all of a sudden, there was the sound of a knife cutting through the air, which sunk into the creature that was biting into Ivan. It howled, and tried to run away when another knife came out of seemingly no where and this one killed the beast. The last thing Ivan saw before passing out was a pair of black boots walking towards him.
Ivan came to in a white room, dressed in a hospital gown, lying down on a gurney. There was a man sitting next to him, dressed all in black with long, black hair down to his shoulders. This must have been the man who saved him. Ivan, of course was very confused as to what just happened. Fortunately, the man was willing to explain. The man's was Kristoff and he was a Bounty Hunter who specialized in hunting down and killing, rogue werewolves. Kristoff explained that Ivan was now a werewolf as well, and that going back to the orphanage was no longer an option. The field hospital that he was in would find him a pack to live with, probably in Norway and that's where he would live till he was old enough to attend Olympus Academy. Ivan, who was supremely confused still and overloaded passed out.
True to Kristoff's word, the field hospital assigned Ivan a pack to live with. Luckily for Ivan said pack was very welcoming and not hostile towards outsiders like some packs were. The Alpha was a very old werewolf who was trying to teach his pack members to be good and loyal werewolves who wanted no harm to humans, so this particular pack was a very good fit for Ivan.
Also true to Kristoff's telling of what would happen to him, Ivan went to Olympus Academy soon as he entered seventh grade, and has been attending the Academy ever since. Due to his age and size, Ivan has become the Beta Wolf of the Academy's temporary pack.
