Lore & Description

Appearance

The Elder Goliath Lizard is a massive reptile, covered in dark green scales that shimmer in the light. Its body is muscular and sleek, with powerful limbs and a long, whip-like tail. It has a wide, toothy maw filled with sharp teeth, and its eyes are keen and alert, capable of spotting prey from a distance.

Behavior & Origins

These colossal lizards are apex predators in their environments, utilizing their immense strength and stealth to ambush prey. They are solitary creatures, fiercely territorial and driven by instinct. While not inherently aggressive towards larger creatures, they will defend their territory against intruders with ferocity. Many tribes revere them as guardians of ancient wisdom in their respective domains.
