Basilisks live in nearly any terrestrial environment, from forest to desert, and their hides tend to match and reflect their surroundings-a desert-dwelling basilisk might be tan or brown, while one that lives in a forest could be bright green. They tend to make their lairs in caves, burrows, or other sheltered areas, and these dens are often marked by statues of people and animals in lifelike poses-the petrified remains of those unfortunate enough to stumble across the basilisk.
