Okay, let me see if I have this right; for Cure of Blood AAs and Demiplane of Blood access:
1. Council of the Nine (36) from Brother Dark Water
2. Emperor Draygun (54) from Brother Dark Water
3. Antraygus, The Sporali King (36) from Boss Harrowan
4. Sendaii, The Hive Queen (54) from Boss Harrowan
5. Master Vule (non-instanced)
Okay, so do missions against Skyra and Bloodeye, whatever they are, not count for progression, but are content and give non-prog rewards?
