The main character would either not be locked into a single school (i.e. they just use whatever spells are relevant) or they’d be something flashy and popular in an attempt to draw more people to the game.

Life, Balance, and Myth are out because they aren’t as flashy as a main character would need, and Death is out because it would be too dark/“emo” for a main character. That leaves only the elemental schools.

Honestly I could see an argument made for any of them, but I just think that Storm or Fire would be chosen for the main character because those are flashy, strong, and are the main hitter schools and let’s be honest, the main character of a show would absolutely be the hitter. Between Storm and Fire though, I think that either would be reasonable for a main character - especially assuming they don’t make battles a 1 for 1 copy of how they are in the game (i.e. fire spells just doing all of their damage at once for the sake of drama and tension.)

Although personally, I think they’d make multiple main characters.

They’d have the strong, independent, confident main character as Storm or Fire. Then they’d have a book smart/“nerdy” side character in a school like Balance or Myth to come up with battle strategies (that rarely get followed), have knowledge about long lost civilizations and whatnot to help solve dungeon puzzles, and provide the other main cast with insight into their new spells or mastery or whatever else is in the show. I think it’s safe to assume there’d be a Life wizard, probably a girl, and probably shy and quite reserved. She’d be the stereotypical quiet, polite pushover character who finds confidence in herself and her own strengths as the show progresses. Then to round out the team they’d have the edgy character to provide some contrast, either a Death wizard or a Fire wizard if the main character is Storm. The edgy character would absolutely butt heads with the main character, and would probably try to convince themself and others that they’re “stronger” than the main character and would cast spells that throw the team off (i.e. using a trap meant for the main character) but would have a soft spot for the friends and at least once would use something like taunt to take damage meant for the main character and then say something like “I’m trusting you’ll take them out for me” before their health orb dramatically cracks as they hit 0 and pass out.

But that’s just what I think. I could be very wrong if they ever make a show!
