Aboleth
Now, these are hard monsters to incorporate into your D&D game.
Aboleths are ancient, nearly-immortal aberrant aquatic creatures (tentacle fish!). They have a shared racial memory that passes from Aboleth to Aboleth, essentially insuring permanent consciousness even as they reproduce and die. And what's more, they are one of the oldest races in existence, quite possibly predating even the gods. Aboleths know that they will survive. They have plans, but are very patient - they certainly have time. There are two major things about Aboleths that make them ahrd to incorporate. One is their back-seat, long term puppetmaster methodology. The other is the fact that they are totally aquatic and useless on land. It's more trouble than it's worth to find a way to make your party breathe under water and then adjust the rules accordingly. A pity, since Aboleths are pretty terrifying in a Lovecraftian sort of way.
