Getting an Altar victory with the Grigori is tricky, I've found. It generally involves levelling up some mercenaries to burn as Luonnotar for altar-building purposes. If you stay financial through the early game, you shouldn't have any trouble with research costs. Focus on getting some non-adventurer units to Luonnotar level, and burn them for the Altars in a non-GPP city. Make sure that said city has plenty of production, though, because that last step is a doozy. Takes forever to build. If you can generate a great engineer or two, save them for the last Altar increment, and you'll have the game wrapped. Easier said than done, right? heh
