What if the demons worshipped by the Baali were eldritch Lovecraftian horrors?

Arkham by Blood is a Vampire: the Masquerade chronicle set in the modern-day nights of Call of Cthulhu's Lovecraft Country. In Arkham by Blood you'll play a Neonate Kindred working to keep the Camarilla's hold on Arkham, Dunwich, Kingsport and Innsmouth secure and free from the corrupting depredations of the evil Baali and the eldritch outer gods whom they worship. You'll need to watch out for not just the Baali themselves, but their mortal cults and apotheosized Kindred from other clans, converted heart and soul to the Baali's cause.

Arkham by Blood uses the Vampire: the Masquerade 20th Anniversary Edition rules.
