Scrawlers are man-sized, cyclopean arachnoids with thick, multihued exoskeletons.  Each is distinct in markings and coloration.  The creatures have 4 legs and 4 arms, with 2 of their upper limbs ending in unique ink-producing organs.

Ambush predators, scrawlers nest exclusively in Ancient ruins, particularly those that attract explorers and scavengers—derelict shopping centers, warehouses, factories, tractor-trailers, etc.  Using their ink-glands, they work in groups to cover their territories with glyphs that mimic Ancient iconography.  Scrawlers don't seem to comprehend what the symbols mean, yet recognize that adventurers are drawn to such images.

While scrawlers seem to indiscriminately mark their hunting grounds without a cohesive "theme", each nest apparently uses certain symbols more than others.  Perhaps that is how different groups identify themselves to their own kind.

In combat, scrawlers try to blind opponents with a conical spray of ink (15' long, 10' wide at the end) before attacking with claws and jaws.  Anyone caught within the discharged ink is Blinded for 3d4 rounds on a failed Saving Throw Versus Poison.

All attempts at communication with scrawlers have failed, and scholars debate whether the creatures are mindless drones capable only of rote mimicry, or actually sinisterly sentient.
