Some of the little Xs are unclear, they were mostly there for my own reference!  The way that it works is that when you choose your race and alignment, each of them comes with something.<br/><br/>So looking at the Cleric sheet (https://dl.dropboxusercontent.com/u/3269630/dwdotcom/Dungeon_World_Play_Sheets.pdf) OR in the SRD if that's an easier format for you, there are choices!<br/><br/>So Good has 'Endanger yourself to heal another', Lawful has 'Endanger yourself following the precepts of your church or god'<br/><br/>Basically you're choosing one of those, first X becomes Good/Lawful/Evil (per the sheet) and the second X becomes the explanation.<br/><br/>Race is the same, except it gives a specific bonus (spell from the Wizard spellbook for human clerics, if I'm not mistaken).<br/><br/>In terms of religion, you are absolutely right!  The field is wide open!  Under 'Deity' it has some suggestions for domains and Petitions, but if you have some other idea percolating, just let me know and we can work something interesting out!
