Artist's description
Tales of Los Abuelos are few and far between but it is said that they are found on every continent. Moving mountains, some call them, a writhing mass of blackened vegetation. All tales that lead to them begin with a hunt to exterminate the grimm, to take the battle to their home and rid the world of them. They found Los Abuelos instead. Survivors had this to say… "We couldn't see anything through the fog… We didn't even know we were standing on it until the ground began rumbling. And before we knew it we were overrun with grimm. They chased us, poured down on us… it was endless." Of all tales, none speak of ever bringing one down. One man surmised his failed attempt with…
"Let them sleep."
