The Vjeci always had an odd religion. Given how instrumental it was to to development of the culture at large, any true and thorough look at their culture must be viewed, first and foremost, through the lens of religion. First, they believe in Dho. To our modern preconceptions of what a religion is, as well as what "God" is, it may appear that this simple fact makes Vjeci religion a simple variant of common monotheism. While certain elements cross over, much much more differentiates it. To understand the religion in its entirety, let us look at where it begins.
The Vjeci were almost paradoxical. On one hand, the Vjeci say that everything is a circle. There is no beginning. There is no end. Yet, they still have a "creation" tale. Most scholars are of the opinion that this particular tale developed out of a time when the religion was far less simplified (though it is not simple) and more tribal. The basic tale goes that Dho was a being from another world. They (oddly referred to as plural here, though not in other places) cut through the fabric of the, for lack of a better translation, space-time continuum, and "landed" on this planet. It was dark, decrepit, barren, and without life.
The tales say that Dho (still plural) worked tirelessly for 20 days and 20 nights to bring life to this planet. They met with failure. For it was not to be. The spirit of the universe was still stacked against Dho, and not willing to yield. It is said that Dho was visited by a Räki. The best translation in the modern tongue would be a "demon-angel from outer space". The Vjeci were not exactly an eloquent people. While Räki have many legends of their own, and indeed play a significant role in early Vjeci tales, at this time, they are a more minor character. It is said that Dho asked: "Why do I fail? Why does life not thrive here?" The Räki answered, in a melodic and hissing voice: "Life...is in the currents of the land. Life...does not exist...here. Life must be brought; sacrificed to...the land."
Dho then knew what to do. He prayed to the stars for wisdom and guidance, begging the universal spirit to accept his offering. Then, s/he (notice, the legends specify that Dho is singular here) drew from inside their robes a dagger. Where this came from is unknown, though its role was instrumental. Dho stabbed her/himself right in the heart, and allowed his/her blood to seep into the land. With its greed sated, the land came alive. Rivers flowed, plants grew, animals were born from the darkness. Then, one day, the Räki that visited Dho came back. He looked all around. He observed the life brought to the land. He saw the greatness bestowed upon the land. He said only two lines is his hissing tongue: "You have done well... Dho. You will...not be forgotten." Before walking away into the sunset.
Thus, the lifeblood of Dho was given to all. Dho did not die however. For all of his/her children still exist. In the sea, the land, the plants and animals. The thoughts of Dho were heard by all, and accepted as the universal truth. Humans themselves are children of Dho, according to Vjeci tales. Of course, that is another story.
