What do you even have to ignore? Lets assume you have a generic campaign level 1-13, set in Kalimdor, current The War Within timeline.

You do not need to even mention shit like Shadowlands. If Grubzug the level 3 Orc Warrior has deep knowledge (or any at all, really) about the Jailor, the Covenants and the Realm of Death, your player is full of shit and should reconsider his character concept.

For your average low to mid level character in pretty much every and any zone, you need to explain next to no metaphysics or big overarching lore or any form of meta plot. You´re in the Barrens fighting Centaurs and Harpys and demon cultists.
