Personally, I'm most happy to have the final piece to complete my headcanon for how my character came to summon demi-Phoenix.

(It continues to disappoint me that the "official" WoL has an apparent aversion to taking on spellcasting jobs. The summoner remains, in my mind, one of the strongest contenders for the WoL's actual canonical discipline, given its many links to the MSQ and game lore.)

Other than that, it was a huge bonus to learn more about Amaurot, and the society of the Ancients. I would easily rank this the best of the four Tales from the Shadows.
