I looked at the items that others had designed already, but wanted something that would allow me to open the box and grab what I needed.

Based off of space limitations I figured out a layout that would give me 12 slots which matched the card categories (9 domains, 1 ancestry, 1 heritage, 1 class/subclass); However the class/subclass is so much larger than all of the others that it become infeasible to distribute them in a meaningful/organized way.

However, you only need heritage, ancestry and class/subclass at game start and tier 3 + 4, so I put them all at the top row mostly organized.

This allows for easy access and separation of all 9 domains and a quick search for the others.

The top row can't be accessed easily, but in the pictures you can see my method for accessing. If you remove the cards from the second row, you can press down on the top of the top row, the cards will tilt into the open space beneath them and the entire stack can be picked up after that.
