Changing the paradigm of Terrestrials to the Lunars' animal emphasis and realigning the Lunars' own background to one closer to the Fair Folk, Attribute-based Charms may suit the Terrestrials more and I decided to allocate Abilities to the Lunars. The following do not have specific Castes such as Full Moon etc. yet. The pattern of the Lunars' Castes may change in time.
Warrior: Archery, Martial Arts, Melee, Thrown, Dodge
Traveller: Athletics, Ride, Sail, Survival, Stealth
Communicator: Performance, Presence, Socialise, Linguistics, Integrity
Mastermind: Lore, Occult, Bureaucracy, War, Investigation
Survivor: Awareness, Resistance, Dodge, Larceny, Medicine (admittedly this is just stuff that didn't fit into the other categories but I think survivor is a good designation.)
Obviously these aren't Caste names but archetypes.
An important point here is that I've decided to break the usual Lunar affiliation with animals (an offshoot of their werewolf background that I've decided to abolish,) now the province of the Terrestrials in a much needed attempt to make them more interesting, and the Lunars' powers are not aimed at flexibility. Instead they deal with one specific role with a sledgehammer blow. Solars may possess multiple Abilities for one task, (the Zenith Caste have Performance, Presence and Integrity) but these Abilities are always spread over multiple Castes. A character with access to all Abilities involved in social combat would be a monster. Especially when given a different meaning to Socialise and Performance. The Warrior has the same Abilities as the Dawn Caste except for Dodge instead of War, which is a better skill set for personal combat.
