toa

So ages ago when i galatic civ ii first came out i purchased my copy and enjoyed it alot for many months, after a while the game got a civilizations esque feeling to it i just couldnt stand to play a new game again, anyway thats totally irrelevant. I eventually got tired of galatic civ and stopped playing it anyway recently i heared about this new expansion and i guess my questions is do i need the Dark avatar expansion in order to purchase toa?
