Name suggestions needed (demonic structures)

Ok, I just want suggested names for things...i'm making a campaign race of demons (player controlled), and i need a few suggestions for names, I'm including the current 'working' name and a brief description.

Hero, Bloodlord: A Pit Lord with Flamestrike and Reincarnation instead of first and ultimate, uses the model of the 'Overlord' creep from Outlands.

Building, Skull Forge: Basicly the Undead ziggaraut, it uses the model for the Shrine with gul'dan's skull on it. I just want a slightly better name.

Building, Summoning Pit: Primary troop structure, uses the Sacrificial Pit allerance.

Building, Temple of the Damned: Same old, except it produces demon spellcasters instead...I'd rather have a more demonic name.

Siege Unit, Infernal Machine: The siege thing from Outlands, just wondering if anyone has a better name.

Thanks in advance!

temple of hate?for the temp
soul forge? for the skull guldan thing
