The Isle of Illusion (only appearance)

Grubs are large invertebrates native to the secret sea.[1]


The Isle of IllusionEdit

Lief, Barda, and Jasmine arrive on the island between Plume and Auron and were confronted by a colony of grubs. At first the insects were harmless, but then began spraying a vapor that paralysed Lief and Barda. Jasmine was able to escape, and returned with Flash to rescue them before they could be eaten.[1]


The grubs are large pale creatures with stumpy legs, and segmented bodies similar to a caterpillar. Two large tubes extend from either side of their heads, which double as both feeding tubes and for releasing their vapor.[1]


The only ability the grubs possess is the bright yellow vapor they use to trap prey. It is vile smelling, and knocks out any warm bodied creature that inhales it. However, it has no affect on cold blooded creatures.

It is also possible to bypass the vapor by covering one's face with a cloth.[1]


Grubs are carnivores. Their primary prey are sea moles who come to beach on their island. After capturing their prey, the grubs cover them in wet clay to preserve the body for extended periods of time before sucking up the rotting liquid through a feeding tube. It is unknown if the grubs secrete anything to assist with decomposition.

The grubs are shown to be very protective of their food, and will defend it even if they end up injured or dead in the process.[1]
