CONCLAVE OF THE BURNING ONE and new necron codex question

[Badtucker]

hi, in the shield of baal exterminatus book the following formation exists for necron players.

CONCLAVE OF THE BURNING ONE
FORMATION:
• 1 C’tan Shard
• 2 Crypteks

now since the new codex has come out there is no individual C’tan Shard entry, what happens now? use the nightbringer or deceiver or transcendent?
background wise the transendiant fits most as its a non descriptive burning C'tan.

[Charistoph]

I don't have the Conclave rules handy, at the moment, but I believe that there is a footnote indicating that the C'tan Shard can be chosen amongst the three. I will double check when I get a chance.
