Okay so here's what I've gathered so far of dragons that are alive:
Bloodline of Roars:
-King: Bagram
-2nd Seat: Gargantina
-? Seat: Erun Eski
-? Seat: Lupowa
Bloodline of Bones:
-King: Banko (currently sealed)
-2nd Seat: Glestnowak
Bloodline of Eyes:
-King: Sigmalio
Bloodline of Scales:
-Queen: Kou Tenran
-12 mature dragons (at the very least)
Bloodline of Wings:
-Ex-King: Crimson
-Ex-2nd Seat: Ferbigott (The snake of Chimera)
-Ex-4th Seat: Nebulim (On a Journey to America with Gilzea)
Bloodline of Roars:
King: Gilzea
Power ranking is probably this (strongest to weakest):
1. Gilzea
2. Sigmalio
3. Kou Tenran
4. Bagram
5. Crimson
6. Glestnowak
7. Gargantina
8. Nebulim
9. Erun Eski
10. Lupowa
11. Ferbigott (is originally more powerful than Glestnowak but weakened as Chimera's tail)
12. Banko (cause he's sealed)
