I just had a thought, you know those 'chants' that are associated with Xau-Tak (Like the one in Death at Sea),
"What carves it's hate upon the monolith? XAU-TAK! Through what do we crawl in silence? XAU-TAK!" What swims in the oceans of the dead? XAU-TAK! XAU-TAK! XAU-TAK!"
What if it's metaphorical for the Mwanu people devolving into the Horrors? The mwanu likely 'carved' that black mask (hate) onto that slab on Mos'le harmless under Xau-Tak's influence, and the line "Through what do we crawl in silence?" Links to a quote from Mod Wilson himself, "There is a scream so loud that you hear it as silence. And this is Xau-Tak", this could mean the Mwanu slowly going mad, and the "Oceans of the dead", those are places Xau-Tak has been, OR, the minds of the Horrors, as they are a violent people, blood and creature sacrifice is likely, as someone mentioned, their Primal Instinct, therefore it's the one thing on their mind. A sea of death, if you will.
