Uhh guys... I might have figured out what Brand really is...
Screw the old vague "spooky spirit posessing a human" trope. Back then in old lore that might have made sense, but right now in new lore we actually have a whole cast of body-snatching-spirit-thingies from outer space. The targonian aspects to be exact.
At first I never thought about it, because Freljord and Mt. Targon seem to be completly seperate worlds to me, but nevertheless they are connected and part of the same universe. But what exactly could Brand be an aspect of? I mean, we got the sun 
, the moon 
, the protector/life 
, a certain constellation 
(bard is not related to targon, but as a celestial being he still needs to posess a material body to act in thew world) and 
, and the stars/the night sky itself 
(who, as a matter-manipulator, can materialize at will).
However, there is something missing. What about a falling star? Pantheon's lore mention a falling star, although he might as well be refering to Aurelion Sol in that moment.
Now imagine the following scenario: celestial body crashes down on valoran while filled with gody power. Usually it would eradicate everything in its surroundings due to the excess energy. HOWEVER, it crashed right into a giant block of true ice that basicially locks up the giant meteroite and the being it contains.
However, it can still form a connection to a sentinent being, even when seperated in matter of space. Pretty much just how the protector "pulled" Taric onto the mountain, it draws a nameless Lokfarian to it and takes him over. But the fall and the long imprisonment in ice that is potentially void-corrupted might have caused some little mental damage (if the being was not insane already before dropping down to earth), and now it's oddly fixated around burning everything. (if that wasn't its thing before, just how pantheon's thing is war).
What exactly that fallen star once was? No clue. Maybe a Targonian that has turned on his friends and was defeated? Aurelion Sol's lore mentions that there had been "more voices" in the past that echoed through his crown. Internal conflicts of the Targonians were mentioned as well, so Brand might be a causality of that conflict. A god banished from the skys to to speak.
HOW DID I NEVER EVEN NOTICE THAT POSSIBILITY?
