Many different aboleth variants have been published in third part products. Here is a listing of some of them. (Servitor races are not listed here.)
These are simple additions to the aboleth family:
- The behemoth, engulfer, manipulator, livyathan, protoaboleth, and larval aboleth swarm appear in Monster Menagerie: Horrors of the Aboleth.
- The nihilith appears in Tome of Beasts.
- The veiled master appears in Pirate Campaign Compendium.
These additions presume that the core aboleth is a member of a family called the [lethid] (invented by Grim Tales). Many lethid are parasitic.
- The mohldaleth, nihileth, rgleth, shibboleth, and true aboleth appear in Slavelords of Cydonia.
- The possessor appears in Possessors: Children of the Outer Gods and reprinted in Forgotten Foes. Not originally a member of the aboleth family, but the lethid are based on its rules.
These additions presume that the core aboleth is a member of a family called the [alghollthu] (invented by Pathfinder).
- The omnipath and veiled master appear in Pathfinder Roleplaying Game Bestiary 6.
- The uldraaghu appears in Pathfinder Adventure Path #121: The Lost Outpost.
- The enisysian appears in Pathfinder Adventure Path #124: City in the Deep.
- The plizeazoth appears in Pathfinder Adventure Path #125: Tower of the Drowned Dead.
As I mentioned in prior posts on aboleth, I decided to use all of these together. I love variety in monster families.
