The demon tablet is the second tablet to be unearthed. According to Castiel, it was dictated sometime after [[Lucifer]] was imprisoned in [[the Cage]]. It contains sections on the demonic influence on the collective tapestry of the soul, and demonic transport to the regions of Hell. It also includes instructions on [[Hellhound Glasses|how to see hellhounds ]] and [[Demon Bomb|how to destroy demons]], as well as containing a number of spells, sigils, and protective circles that can be used against demons. The most notable spells on the demon tablet are instructions on how to close the Gates of Hell forever and how to create an [[Portal|interdimensional rift]]. It is currently in the [[Men of Letters Bunker]].

The angel tablet is the third tablet to be unearthed. It was created sometime before Lucifer was imprisoned in the Cage, and he concealed it in one of his crypts. The tablet contains multiple spells, sigils, and protective circles that can be used against angels. It appears to contains contain angelic [[trials]]to seal the gates of Heaven, though their purpose was they were not revealed. It also includes a second spell, personally placed by Metatron, that can banish all angels from Heaven and lock the gates. Metatron used the angel tablet to enhance his powers to make himself semi-equivalent to God. It was destroyed by Castiel to weaken Metatron and reclaim Heaven. Before his death, Kevin was able to translate the entire angel tablet into Proto-Elamite cuneiform. His translations remain in the Men of Letters Bunker.

The tablets were especially prominent in the storylines of Seasons 8, 9, 13 and 1315.* The only season since their introduction that the tablets have played no role in at all is Season 12.
