here is another descripton of hell from the Fatima apparition: As Our Lady spoke these last words, she opened her hands once more, as she had done during the two previous months. The rays of light seemed to penetrate the earth, and we saw as it were a sea of fire. Plunged in this fire were demons and souls in human form, like transparent burning embers, all blackened or burnished bronze, floating about in the conflagration, now raised into the air by the flames that issued from within themselves together with great clouds of smoke now falling back on every side like sparks in huge fires, without weight or equilibrium, amid shrieks and groans of pain and despair, which horrified us and made us tremble with fear. (It must have been this sight which caused me to cry out, as people say they heard me). The demons could be distinguished by their terrifying and repellent likeness to frightful and unknown animals, black and transparent like burning coals. Terrified and as if to plead for succour, we looked up at Our Lady, who said to us, so kindly and so sadly: You have seen hell where the souls of poor sinners go. To save them, God wishes to establish in the world devotion to my Immaculate Heart. If what I say to you is done, many souls will be saved and there will be peace. from: [NC Register](https://www.ncregister.com/blog/on-july-13-1917-our-lady-of-fatima-showed-a-vision-of-hell-and-taught-us-how-to-avoid-it)
