Charictor ideas.

Magus: First to realize the potential of blood magic. Developed the altar, the blood orb, the alchemical chemistry set, the basic spell table, and rituals. Teacher of the lot, helping the others through there journeys. Started experimenting with blood magic after years using other forms of magic. A bit of a recluse, but friendly once he knows you. He helped the others by giving them a foundation to work off of, pioneering the basics of blood magic, then learning from his students as the expanded upon his work.

Vlad: Older brother of Demir and Bella, and eldest of the three. Lived with his brother on a trade caravan, and helped the healers make medicine. After the caravan was raided by bandits, they survived the raid by hiding under an over turned wagon that had belonged to Bella's parents, meeting her there. They then started wondering until they found the house of Magus.

Vlad is skilled in alchemy, learning basics from the healers. This is what got the three of them inside Magus's door. After showing magus what little he knew, Magus started teaching him blood alchemy. Cleaver, calm, and has a level head. Does what he can to help his younger brother and sister, as they and magus are the closest thing to family he has.

Demir: Skilled in the art of spells, younger brother of Vlad. Learned the basic spell system from magus, then expanded apon it with the help of his brother to make the advanced spell system. A little wild and careless, he has gotten close to deaths door on more then one occasion when practicing blood magic. Not as patient as Vlad or Bella, but still very skilled at blood magic. He is willing to give up his life if it means the others will live.

Bella: The quiet, shy girl of the three. Youngest by about a year, her parents were the owners if the trading caravan. She helped the others live by beckoning them under the overturned wagon during the raid. Skilled with the summoning and taming of demons, she helped magus create the summoning ritual after realizing the potential of the other world Magus discovered that up until then magus had only used for making bound tools.

She prefers to let her brothers take the led. Being an only child, Vlad and Demir were the first siblings she ever had. While she shy's away from people, she feels right at home talking and working with demons. While not as skilled at spells as Demir, her small army of demon "Friends" are more then enough to help her hold her own in the field.

Tiberious: A wanderer that stumbled into blood magic accidentally, then discovered Magus when he passed through the small village near Magus. Trading the only thing he could offer that Magus would find interesting, knowledge, Magus agreed to take him in as an apprentice. Helped Magus by experimenting with sigils, as a more portable way to use personal rituals. Latter he helped Magus create bound armor, creating the sockets that hold the sigils and realizing the need for blood shards in the armor.

A black smiths son who left is search of knowledge of the arcane in order to empower himself, he wandered the lands for a little over a year before finding Magus. A little greedy in his quest for power, he is always trying to find sigils to boost himself. He was originally the one to let the kids in when they found Magus's door. After they proved there worth as blood mages, Tiberios pushed them to got beyond what he and Magus had done. He was the one to push the group into writing about there journeys into the forbidden magics as a way to pass on there knowledge to others.
