species pecking order
often called “the titan generation” due to all species that fall into this category are massive in size. the titan races are believed to be the first wave (and most powerful) of species upon obraxsis. generation 0 species typically have around 80hd and are natural planeswalkers. but births and maturity tends to take centuries or millennium.
