Loads of ideas. 

We can go worldbuilding in multiple ways. Random by asking ChatGBT to create some gods for us and then we edit them OR each player makes their own 3 or so divinities. 

As a head of the pantheon I suggest we go away from Light is at the top trope. What if this time we'd have a Time deity? Time has, after all, control over everything in a way or the other. We could also go for like Chaos as the leader. Not evil, not good.

Giants would be awesome to have their own empire but as well the "smaller races". The Goblins, the slimes, kobolds etc. It's been bugging me for a long time that the minor races were always seen as tribal/monster like.
