Crimson Longinus
Legend
Which is crazy way to do it. Your fiction shouldn't be dictated by mechanical changes made for playability.The cosmology shifts overall in 1e to 2e, and 2e to 3e, was part of the larger story of the D&D worlds and did not change history; whether you like the changes or not, they happened in universe.
Which is the sane way to do it.The 4e cosmology shift straight up rewrote the universe, and the stuff they're doing now is doing that too.
