There are several types.. The books just mentions three specifically though. As for our Ainz he think he have passed thru the three mentioned stages on his way to reach Eclipse Class. Partly because it seems like you need certain levels for the three stages mentioned i.e Chronos, General and Wiseman.

Notice that Ainz have several race levels unaccounted for in his character sheet so there might be a surprise or two there. The WN for instance mentions that he got five levels of Demi-Lich which would explain some odd stuff
