The material world has faced great dangers in its wake, Countless invasions from beasts from other worlds. However it always held the greatest trump card out of them all, The Tarrasque. This last resort beast can cause the destruction of civilizations and bring many invaders running back home. And when it is done it retreats deep underground to slumber again. However a group of mind flayers stumbled upon the sleeping creature in all its great glory. Seeing the opportunity to reclaim their kingdom with a mighty beast such as this they created a hive around it. When completed they built the gestalt pool around its head, granting one tadpole to wiggle its way into the creatures brain and start the ultimate process. It took decades but eventually the beast awoken once more, yet not as a weapon of the material realm but as a member of the illithid hive mind. Combining its mighty strength with illithid psionics it will lead the charge to once again bring all realms down on their knees to the illithids great empire. |
