Re-reading Forever Faithful with an eye towards data-mining for Sarna, I find that final chapter preceding the Epilogue raises some questions.
When Precentor Albany Clarke lands on Wayside V she is absolutely sure that it is a Wolverine colony, and she's also sure that she can easily recruit them to fight against their common enemy, the Clans. That does of course indicate some WoB knowledge about the Wolverines that we previously couldn't be sure the WoB even had.
The WoB found the colony through HPG parts being sold in the deep periphery that weren't of WoB manufacture. But she never even considers secular ComStar or a Clan other than specifically the Wolverines as the possible source - why?
However, when encountering Paul Moon for the first time she recognizes him as an Elemental and takes this as confirmation of her theory that the Wayside V colonists are Clan and must therefore be Wolverines. Which doesn't make sense, as Elementals didn't exist yet when the Wolverine Annihilation occurred.
