SPOILER!!: other special account characters you may see around
Name: Tearlung
Role: Gringotts Head Goblin
Background: Tearlung has worked as the Head Goblin at Gringotts since January 2090 and claims to have over forty years of goblin banking experience in the private sector. It seems he transferred from one of the European branches but not much else is known about him by British wizardkind. He does, however, seem very effective at his job, even if he is rather grumpy and prone to mistrusting "wand-bearers." Because of this, Tearlung will say as little as possible to any witch or wizard he comes across if he can get away with it.
Name: Sturnik
Role: Gringotts Head of Security
Background: Sturnik is a rambunctious goblin who has always held the high ambition of being the first goblin in the Wizengamot. He left his homeland of New Zealand at the age of thirteen and found a place in Diagon Alley. His emotions get the better of him at times and he lashes out. He has held the Head of Security position at Gringotts for the past two decades. Sturnik often accompanies the more suspicious Gringotts patrons to their vaults, and he's good to have around when things get a little dangerous.
Name: Sagni
Role: Gringotts Vault Manager
Background: Sagni keeps the vault records up to date and is often on hand to escort people down to the depths to make their deposits and withdrawals. She rarely converses with wizardkind except on official business, which is probably for the better. She has always wanted her own wand and holds some resentment for the accident of her birth that prevents her from obtaining one. However, she is very skilled with goblin magics and comes from a long line of goblin master crafters.
Name: Gringotts Goblins
Role: Gringotts Goblins (various roles)
Background: It takes hundreds of goblins to run Gringotts Bank successfully. No matter where you go within the confines of the bank, there is always a goblin around the corner. Who you run into at the bank will depend on where you are heading. Most wizardkind, though, only interact with a small amount of goblin employees -- ranging from the tellers who provide banking assistant to the cart drivers who escort people to their vaults to sometimes goblin security (who you do not want to mess with).
Name: Bunny the Dragon
Role: Gringotts Dragon
Background: Bunny is a rare hybrid dragon, a cross between a Chinese Fireball and a Hebridean Black, that resides in the depths of Gringotts Bank, safe-guarding the most prestigious of vaults. She is about 28 feet long from tip to tail and closely resembles a Liondragon save for its scales are coloured black and purple eyes. She has a strict diet, though has a taste for (and has tasted in the past) both human and goblin flesh. The thing she fears most is the sound of clankers and the threat of an inevitable punishment.
Name: Demian Andromalius
Role: Coffin House Ghost
Background: Demian was born into pure and noble heritage and was once the most handsome creature alive. After a number of courtings, which all resulting in the mysterious death of the lady in waiting, he eventually made plans to marry Tabitha. Following an episode of him getting a wrinkle by his lip and lashing out that he would never marry a half-blood, he was murdered by Tabitha on their wedding day and he came back as a ghost, forever beautiful and forever bound to the area in which he died.
Name: Korpsit
Role: Arkie Alderton's Kwik-Repair Shop
Background: Korpsit comes from humble beginnings in Sweden, where he was to follow the family tradition of mining gold. Following the unexpected death of his parents in a collapsed mine accident and moving in with miner relatives, he left, looking to find his own destiny at fifteen. He wasn't hired anywhere he went, acted out, and went to prison where he joined a number of rebel goblins. Their efforts, which never were progressing, were wasteful to him, so he found "friends" in Knockturn Alley and landed his first job.
Name: Madam Hildegard
Role: Starry Prophesier Peddler
Background: Madam Hildegard was born with yellow eyes and green skin thanks to her less than skillful potioneer parents. She was then given away by her parents, who were embraced by her appearance, and lived in the streets. Years went by and she went her own way, finding an old cart and filling it with the things she had learned. From town to town she went, only to be stoned. Snapping one day, she attacked a teenager that stoned her and found refuge in the only place where stones aren't thrown at her.
