Hey everyone! It's been a while! Let's fix that.
So here's a set of magical heroes and villains.
Aeon the Archmage
The preeminent magical practitioner of the world for the past century or so, a former occult detective turned wizard by the previous Archmage after that man was stricken by a powerful curse. Has been a leader of a few major groups of guardian mages and mystic heroes like the Order of the Golden Dawn and the Pentacle.
Blackstone
A former college student who came into possession of the Night Stone, a mystic gem created to absorb and entrap all black magic and evil mystic entities. Now as the "good" dark wizard Blackstone, he has embarked on a mission to use the Night Stone to remove all mystic threats from reality. Because of its dark magic absorbing properties, the Night Stone allows Blackstone to use dark and evil magics without becoming corrupted by them.
Janus the Overseer
Janus is an Overseer, an order of Primordials that have appointed themselves to be the custodians of all reality, while observing a strict code of noninterference in the internal matters of the realities they tend to. However, an Overseer can personally enter a particular reality, but only if it gives up the majority of its considerable cosmic power. Janus is one such Overseer, and has entered this universe in order to keep an eye on two fallen Overseer imprisoned in this reality. He has usually taken the form of some sort of divine entity or powerful wizard, and in the modern age has assumed the form of a cosmic-themed magus clad in alien armor.
And now for the bad guys!
The Thaumaturge
The Thaumaturge was originally a cautionary tale told to aspiring wizards of the dangers of obsession in the magical world, and what could happen if one tried to master all forms of magical practice. But over time, stories were piled onto stories, until the Thaumaturge became a kind of ultimate magical boogeyman, an archmagus who was practically an evil demigod. And then it turned out he was a real person. Ever since his sudden reappearance and confirmation of his reality, he has become one of the greatest active mystic threats on Earth, and a major adversary to Aeon and his allies.
Mortis Rex
Mortis Rex is an American necromancer who travels through the nation's more isolated and rural communities, adding their populations to an ever growing army of the dead, alongside his own personal band of followers, the "Deathwalkers." He is an archnemesis of the Rising Stars, the team of teen and young adult heroes from the Xidorn International Extraordinary Academy, and in particular of Necro Girl, who used to be one of Mortis Rex's acolytes.
Doctor Crypt
Doctor Crypt is a former occult detective like Aeon and was a bitter rival of him. When Aeon was chosen over him for inheriting the title of Archmage, he made a deal with a group of ancient psuedo-demonic beings trapped on Earth for revenge. He lured Aeon and the Golden Dawn into the dimensional prison of these entities, resulting in the deaths of all involved except for Aeon, who managed to escape and trap Crypt and his masters in the dimension. For his failure, Crypt was punished by his masters, and over time became transformed into a horrific humanoid abomination. But now he has returned to finished what he started so many decades ago.
. Icestorm is one of the most eye-catching designs you've made, though- I can easily see this guy becoming a "Spider-Gwen" situation where a one-off appearance turns into more because of fan demand.
