In the Past

One of the big additions to D&D for 5th Edition is the idea of a “background”. Similar to secondary skills from 2nd Edition or traits in Pathfinder, a background is what your character was before they were an adventurer, their starting profession. It’s a small addition but a pretty cool idea. Some examples include a hermit, soldier, acolyte, or the sage, which includes a whole bunch of sub-specialities. Such as “astronomer”. So now your rogue could have spent their youth looking at the stars. Usefulness of backgrounds might vary.
