Reef Automaton (animal)
Reef Automata are curious contraptions that have been found in the Tower Isles. These strange machines seem to be connected somehow to the various structures that dot the sea, as many have been known to patrol the sunken ruins and ward off trespassers. They are highly aggressive when encountered by humans, though do not extend this violence to the native wildlife of the sea.
The coral covered cogs and whistles of the reef automata crunch and tick with each of its movements. We've been watching the contraption patrol what may have once been a villa for several hours now, and it has not deviated from its path even once. My companions are wary of taking on such a thing, though after seeing it now, they've grown increasingly more confident in our abilities.
If we can manage to snap off some of its corroded limbs, the automaton won't have a chance to strike back. That is of course, if it doesn't have a trick up its sleeve.
