Kadamel

Fiends spread corruption to places across the planes—every place they can reach. Kadamels guard the most crucial pathways and holy sanctums. They hold a patient vigil, never distracted from their task. Most crucially, they watch over planar portals, barring passage to all but the most powerful fends. When encountered, these archons speak and react little. They rarely even move or react, though they readily accept any assistance in defeating fendish invaders. Even this, they accept with only an ominous nod.
