New guy in the hobby, and I have NO idea where to start (AoS)

Order fights chaos, chaos fights order, death fights everybody ect ect, the order Lizard men are like aztecs fighting to destroy chaos, elves fight dark elves, that doesn't even provide a drop of info, what you're asking for is roughly a few dozen paragraphs, Warhammer is famous for massive amounts of information, so what I recommend, is going to gw's website and find a faction that looks good, like the out of production Tomb kings, which are undead that use massive metal beasts, or the skaven, evil hominid rats with advanced tech forged through dark gods, Tzeentch - Chaos God of magic and fate, then, look up lore videos on YouTube, like about Khorne, the God of blood, war, and skulls, and if you don't like what they're about, find another faction, look into lore, and since these videos often lead around (gods, events, threats) you'll often find information about other factions in the same video, helping you down the rabbit hole

OH and this hobby is rather expensive, so advanced tip, vallejo paints are cheaper and just as nice
