I'm a pretty new player. I have played one campaign to completion and am in the middle of two other ones with two different groups. I've never made any homebrew content, and I only have a pretty basic understanding of the game from a player's perspective.
I am looking to create a homebrew race but have no idea where to start!
This species is a bug race with two 'factions' if you will. Each has a different appearance and a single special ability, silk weaving and a knack for sensing vibrations of the ground.
I have illustrations
I have some ideas on how their culture works
Where should I start with creating this race? What should I know?
