1. Common aboleth have a life span of about 2,000 years. Greater and noble aboleth live to be about 3,000 years old. Rulers can live as long as five millennia, while the grand aboleth may well be immortal.
This is from Dragon 131.
Based on this and the common conception that aboleths are immortal and that 2e did not typically utilize the concept of monster progressions, per se. Would it not make more sense to develop an outline that deatils what improvements a aboleth gets as it ages instead of following the 2e ideal of several different aboleths?
Also, in deference to the core aboleth, wouldn't the concept of genetic memory thus imply that an aboleth possesses great intelligence, more so than the 15 INT given to it in the MM? Considering the genetic memory of it's predecessors could be host to countless thousands of consumed memories, would it not only be feasible, but likely, that an aboleth would possess a 20+ INT at 8 HD?
My next thought is based on the thought process that aboleths possess great mental capacity and rule through power, not personality. Is it possible to make their psi-like abilities Intelligence-based?
Please don't take this as derision towards the great efforts you all have made towards these conversions, as it is good to see others still embracing the great malleability of 3.5.
Thanks for reading, keep up the great work.
