Great post Bakura - could you just clarify something for me please?

You mention this team for Mayan (Necropolis);

the Team for achievement goals:
*Gambler Ed-fortress/cosmic
*Necropolis-vipers/cosmic
*Dracula-reapers/cosmic/yellow (or sacreds)
*M. Mayan Priestess-singularity

Where do you get Fortress talismans from, what colour are they, how many in the set?
Can't see them in the Compendium or in Deathbat's talisman spreadsheet - could be going blind

Cheers - JawS
