This egg is almost completely hairless. Its outer shell is impenetrable. There's nothing that can stop this egg from hatching, it seems.
The earliest people of the island likely had to deal with this beast when establishing Arkian civilization.
Logasters are said to look like a fat bear and are mostly hairless with the exception of their prominent eyebrows and chin. Their skin is extremely tough and leathery which makes them invulnerable to sharp objects, bullets, and arrows. Logasters, however, do seem to have a weakness against fire and avoid it at all costs.
It is thought that a Logaster could devour a whole horse in a matter of ten minutes. If that's not satisfying enough, they will continue attacking and devouring anything that they perceive could be food and be eaten.
