To start navigating, I suggest pathing to NPC Yakantum (https://bdocodex.com/us/npc/46034/). Come out from his camp, turn left follow the road, and you'll see a big arch rock formation. Continue up ahead just very slightly, you'll see little pebbles being stacked into piles to the right side on a big flat rock. There's also a small stone-lamp post. From there, turn left. After moving for a bit, you'll see a really tall stone formation on your left. Go past it, up ahead is the little worship zone you're looking for.

At the upmost platform, you'll find a big man with diamond chequered garment. Thats the knowledge NPC
