If this is the wrong place, let me know where to go.
I'm trying find a short (under 25min) that was on youtube. I watched it on TV, unfortunately with no watch history. This was in with in the last 2-3 months. Title is one word from what I remember as is the channel name. The names were not in English. Short is possibly not native English. Next to no dialogue from what I remember. Not slasher horror, but dread, seemed well produced and filmed with some quality imagery.
It is about men in plate armor (knights, solders, etc) going into the forest and encountering a woman. The woman may be a witch, hag, oracle, etc. she has pale white skin, appears to be nude but her long hair hides that. the men are driven mad and begin to fight and kill each other. In one of the scenes she has long fingers that have black ichor on them. In another scene she steps into a pool of blood, the pool is in the roots of the trees.
AI and google isn't helping the closest I could get was love death and robots' jibaro. jibaro is very similar and may have been the inspiration or vice versa.
