Lore... as in for Terraria? Or just games in general? If just Terraria then be sure to remember that 99.9% of it is just pure speculation as there isn't very much to go by.

If you're doing a lore-based channel I recommend having an accent and a low and quiet voice. It gives of a mysterious vibe.

I say just do what you want to first. Don't restrain yourself to specific things at first, and use the time to figure out what you want to settle on in later times

Thanks. Not Terraria lore, for sure. I am actually considering doing it for Darkest Dungeon. That game has really cool lore that remains mostly unexplored by a lot of its fanbase.
