The karka (Levvi's Leviathanus Carcinus) are aquatic creatures from the depths of the Unending Ocean that have recently been forced onto the surface of Tyria by an Elder Dragon, after the defeat of Zhaitan by Pact forces. They settled onto Southsun Cove and created a large hive on the volcanic island.
Karka are a deep ocean crustacean race which is capable of creating extremely hard exterior shells. As the karka grow and become older, they make harder shells, eventually becoming impenetrable. The only time they are vulnerable is when they're hatchlings or when they shed their shells for larger ones as they grow.
After their initial assault on Lion's Arch, Head Researcher Levvi with the aid of her krewe and adventurers developed an acidic solvent to help dissolve these hard shells in order for the Lionguard to counter-attack. As karka are harmed, pieces of their armor gets knocked off.
The karka are an ancient race who spent most of history in the ocean depths. According to Zommoros, they haven't been seen on the shores since ancient days when the world was "emptier" and the continents were shaped differently. The karka as a race have encountered the Elder Dragons before in the past, so they know the dangers they present, which gave them the knowledge to avoid Orr and the remaining risen when fleeing from the deep sea Elder Dragon.
When the Consortium investigated Southsun Cove in efforts to find a tropical vacation location, they unintentionally provoked the karka, and were mostly wiped out by them. The karka then tracked down the survivors who fled to the mainland, attacking Morgan's Spiral, Garrenhoff, and Lion's Arch - making their presence known to the rest of Tyria. The Lionguard, led by Inspector Ellen Kiel, launched a counterattack and greatly diminished the karka's presence on Southsun Cove, killing the island's only known Ancient Karka in doing so.
