My son has custom made and is playing with a thief/Necromancer that he calls
a Dark Mage. The only way to catch any of the Dremora's is with a black soul
gem. My son has been cataching all sorts of souls and has about 40 of them.
So far has 4 Black soul gems with Dremora Souls. He said he tried every type
soul gem in the game to capture a Dremore and until he started using Black
soul gems he was unable to capture one. He also captures road agents souls in
them but don't let a regular Mage find out or they gang up and attack you by
sending Battle Mages from the Mage Guild out to Kill you.

Really? They send mages to kill you? Sweeet...
