Rather, the Robel-Akbel we know is a Spitewarden! It seems the story of him dying is actually true, and a Spitewarden is posing as him in the Shadowreign timeline. Nitpicking, I know, but there was a Robel-Akbel and he died.
My current guess is there is a Spitewarden for each race.
"Robel-Akbel" is the Tarutaru (and the mostly unusually motivated? His motives in the Windurstian quests seem good, albeit a bit shady)
Haudrale is the Elvaan
Aquila is the Hume
Lazros is the Galka
and I'm putting my money on Lehko Habhoka being the Mithran Spitewarden.
This would also make the Spitewardens all male, and Lilith seems like the kinda chick to run around with 5 guy underlings
These chess metaphors are getting old, between Schultz, Windurst, and now the main storyline!
And it's good to see Altana playing a bigger role in this expansion (although expected), and I guess we can now correctly assume the Cait Siths are some form of avatar. (Celestials were called to heaven by Altana, etc etc at least so the legends say)
