D&D Parallels:
The faery sage occupies the gray area of elf Druid and invoker. This build is your Super Space Control Ship as the Kzinti Dreadnaught is to Starfleet Battles. The idea is to offer general control over non-military sectors. Your capabilities are medium to strong support to the specialists like elf mystic, halfling rogue. Aid is another facet of this combination. You belong to the triad of dwarf war hero/faery sage/human merchant: the cog that drives the wheel.
