Aboleth

The first of the aberrations spawned from Guhvian that did not resemble their progenitor, aboleths lurk in ocean deeps and underground lakes. They are capable of controlling minds and seize control of aquatic life-forms, making them into slaves. Their dominance makes appear like gods to those they control. The lesser gods broke the burgeoning underwater empire of the aboleths, freeing their slaves.
Aboleths have never forgotten. They have flawless memories. They pass on their knowledge and experience from generation to generation. Thus, the injury of their defeat by the lesser gods remains perfectly preserved in their minds.
Aboleths’ minds are treasure troves of lore, recalling moments of history with perfect clarity. They plot patiently and intricately across centuries. Few creatures can conceive of the extent of an aboleth’s plan.
Aboleths dwell in watery environments, mostly ocean abysses, deep lakes. In these domains and the lands that adjoin them, aboleths retain a god-like presence to many, commanding worship and obedience. When they consume other creatures, aboleths add the knowledge and experiences of their prey to their eternal memories.
Aboleths use their telepathic powers to read the minds of creatures and know their desires. An aboleth uses this knowledge to gain a creature’s loyalty, promising to fulfill such wants in exchange for obedience. Within its lair, the aboleth can further use its powers to override senses, granting creatures, such as its followers, the illusion of promised rewards.
The aboleths’ fall from power is written in stark clarity on their flawless memories, for aboleths never truly die. If an aboleth’s body is destroyed, its essence lies dormant in the location that it died until another aboleth retrieves and absorbs it.
Ultimately, aboleths dream of revenging their defeat by the lesser gods and regaining control of their former subjects on the grand scale they had once plotted. Aboleths have had centuries to plot and to prepare their plans for perfect execution.
