Raziël, the enigmatic angel of Ioun, serves as a rare and direct link between mortals and the divine realms of knowledge. Revered as one of Ioun's most powerful agents, Raziël occupies a unique role among the angels, particularly in their connection to mortals. Unlike their serene counterparts who focus on organizing heavenly knowledge and divine truth, Raziël actively engages with those seeking divine insight on the material plane. Whether receiving prayers, granting clerical powers, or forging pacts with warlocks, their presence serves as a bridge between mortals and the hidden wisdom of the cosmos. Their autonomy and capacity for individual thought far exceed that of most angels, allowing them a greater degree of interaction with the mortal realm, especially when channeling Ioun's mysterious and vast knowledge.

Mortals rarely witness Raziël's true form. Instead, they appear through dreams, visions, or sometimes speak directly into the minds of those they deem worthy. In these interactions, they often take on the appearance of a planetar—a striking androgynous figure with ageless, green skin and wings that inspire both reverence and awe. However, those who glimpse Raziël's true form are met with something far more unsettling: a towering throne of interlocking wheels, eyes, and wings—a sight both terrifying and incomprehensible to mortal senses. Raziël's presence carries a cosmic weight, as they always discern truth from falsehood, and their knowledge encompasses all languages and forms of communication. Genderless and mysterious, Raziël embodies the hidden depths of knowledge, shrouded in both awe and secrecy.
