Need Hebrew help

Hello. I've hit a bit of a conudrum and need help, and 4chan seems like the right place to turn to.

You see, I am looking for a name in Hebrew. I know that "Merkava" means "Chariot". However, I'm looking for a way to expand it to "Chariot of the Gods" or similar. Could anyone help?

I'm curious, any reason for the t there? I thought masculine verbs didn't get modified <.<
