When choosing a Warlock and their otherworldly patron there is only one of the three options available. Only the Fiend shows up, the Great Old One and the Archfey aren't available. I spoke in the HipChat about this and we found that no one added either option in the data file.
Can you please cite where in the SRD5 this information is found?
Note that I may have misled you, apparently the SRD5 references items that don't exist it itself. We may not have the rights to include items from the Players Handbook or other books.
SRD5 contains everything allowed, reporter is asking for PH materials that are not licensed.
