Izzurius is a black and grey avian demon who wears a hoodie and black robes adorned with various potions and belts that wrap around him. Izzurius wears an augmented mask and glass goggles to protect his face from the chemicals he uses when mixing potions. While the goggles can be removed, his mask is permanently attached to his face due to an incident that happened when he was younger that melted off most of his beak. Izzurius also has extremely long eyebrows that he keeps properly maintained in the rare times he’s not working. He wields a staff with an hourglass at the top that he uses to time himself while performing certain experiments. Underneath his clothes he has multiple tailfeathers and a large insignia of the Pride symbol on his chest. His job is to mix alchemical ingredients together to create magical potions that have a variety of different effects. If the new spell effects are vetted by the Infernalords, he creates different articles of clothing and enchants them with these spells. These magical potions and clothes are then shipped throughout different areas of the Infernalands for a profit. Spells range from invisibility, to illusory/hallucinatory effects, to temporary enhanced strength. Spells can mix together for hybrid potions, and there are different levels of potions for every preference out there to fit each demon’s desires. There are also prohibited dark spells that the Infernalords deny and prevent any from being further manufactured or shipped. As tempted as Izzurius has been in the past, he has remained loyal to the Infernalords and not practiced any spells or dark magics hidden deep within the tower’s floors.

Izzurius is a workaholic, and is always looking for things to do. He finds relaxing to be boring, and feels that time is knowledge. He works almost 24/7, using a special type of magic coffee called Demoncaf to help him stay awake. Because of this, Izzurius can get an immense amount of work done for his research, and is therefore the second wealthiest Infernaling in the Infernalands, only just below Hivemine. He takes immense pride and satisfaction in his work and knows that he is the best of the best when it comes to taking his job seriously. Izzurius hates slackers, and can easily tell when someone isn’t giving it their all. He’ll taunt his employees in a passive aggressive manner, sometimes throwing potions at their feet to make them work harder. If the Infern (employee) doesn’t improve, he exiles them from the Prior Spire, leaving them to fend for themselves in the cold, black desert at the base of the spire.
