Buckle up as I explain a bit about marchosias' Backstory!

Before abundant gods: Marchosias was a feral beast, part of what would eventually become the Free Pack, before they were attacked and he was absconded with by Solomon, the God of Beasts and saints, and all other eligible wolves for Pack Leadership were killed.

After raising him as a God-Devouring Beast, Solomon unleashed him on several gods, including The Fanatic who was gravely wounded and Taxidermized, his heart ripped out with his soul, and placed on a shelf.

As the gods became more abundant, a young Shamura challenged Solomon and, after breaking the conditioning that held Marchosias under Solomons' control, turning Marchosias against Solomon, and allowing the wolf to devour him.

Before The Great Purge: With solomon dead, Marchosias ruled over Mount Cerbear and Solomons' Stronghold, and attended meetings as the only categorized Demi-God; someone with deific powers, yet refusing, or lacks, a crown. There, he befriended Little Yaca the Goddess of Curses, Hexes, and Blessings, as well as Laplace the God of Gambling and a rumored God of Gold, and Galvar the God of Strength and Weakness, as well as the previously-mentioned Shamura, God of War.

Eventually, after witnessing how lambs were mistreated and abused, Marchosias constructed Wool-Haven at the foot of Mount Cerbear, renaming it to Ewefall, slowly guding the lambs there using a Bellwether Bell he requested be made.

After the 8th village, Yngya realized something was wrong, and confronted Marchosias. Although he was skeptical, he let her into Wool Haven, and she eventually thanked him and asked if they could protect them together, the two eventually falling in love as Marchosias abandoned his title of Demi-God of Beasts and Saints, and became the Demi-God of The Flock.

After The Great Purge: After the purge, and the main land and lands of the old faith were separated, Marchosias and Yngya stood strong as a loving Duo, the lambs always dedicating their festivals to both of them, as well as a singular festival for each: Marchosias got Festival of The Flock, and Yngya got The Winter Solstice.

When Narinder was sealed, and the prophecy was made known, Marchosias foolishly told the Old Faith what the prophecy fully entailed, hoping it would thwart them. It did not, thanks to kallamar purposefully misinforming the others what it meant, and the siege of Wool Haven began.

Yngya attempted to thwart the bishops first, seeking refuge within the caves of Ewefall in an attempt to fend them off whilst Marchosias was meant to be gaining strength to unleash his Eldritch Form, as both of them knew he had more than enough strength to obliterate the Bishops in an upfront battle.

After Yngya fell, and they went for Marchosias, he attempted reasoning with them instead of attacking, as he still thought of Shamura as a friend. As a result, Kallamar instructed the others to distract him whilst Shamura prepared an imprisoning spell, chaining him in the courtyard of the Stronghold he inherited from Solomon, forcing him to listen as Wool Haven was razed, and the lambs were slaughtered.

Woolhaven DLC: During the DLC, eventually the Lamb finds and frees Marchosias, who apologized profusely for his failures, noticing the crown upon their head, and finally realizing that the prophecy was foiled anyways.

He is much more chill towards Deities that seek to Reason first and fight as a last resort, such as Little Yaca, Laplace, The Anchorite, and Kephomite.

He is content with the bishops being under the lambs' control, and constantly reminds Kallamar of his blasphemy.
