What fragments do I need for Elder in Shaper's realm fight ?

I'm having a brain freeze on this. Which fragment set do I need to use to complete this quest. It does not seem to be via Shaper or Elder guardians fragments (tried both of those - doesn't get me to Uber Elder, just Shaper and Elder)



I'm assuming they mean Zana by the reference to the Rogue Cartographer. Is there something I need from Zana as well ?

Thanks. So three more to go for me then :-)

Specifically, the fragments listed here.
