When you're starting a homebrew D&D campaign — building your own adventure in your own world — it's okay to not have everything planned out in advance.
People use the word 'realism' or 'realistic' a lot in gaming, and it's something to consider, but for an aspiring Tabletop RPG game master it's toxic to concern yourself too much with it.
I remember when I decided to start my first Dungeons and Dragons game as a DM, and found about a month into it that I'd accidentally created my own campaign world.
The time has come for many of us to level our alts, as Shadowlands is entering the lull period where we have accomplished most of what 9.0 had to offer to our mains and are eagerly waiting for 9.1 -- or we're simply in the mood for a change of pace.
Your first character has entered the Shadowlands, completed the Campaign, chose their Covenant, and started progressing the Covenant Campaign.
Okay, so you've decided you want to create your own world in your weekly tabletop game.
If you're a big Titanfall fan who played the heck out of that game and were disappointed that it didn't have a longer single-player campaign and, like me, considered Overwatch as a potential replacement for that running and shooting itch you no longer had a way to scratch, it's still not going to happen.
I admit, I kind of dawdled on this one.
