The elusive nature of the chapter has also made it difficult to ascertain the full strength of this fighting force. Whether or not the Eternal Legion suffered any crippling mutations has yet to be seen, but the Chapter's practice of replacing limbs with bionics could allude to the removal of mutated limbs in an effort to hide these deformities.
Through a great deal of speculation on the Inquisition's part, it is believed that the Eternal Legion were actually created during the ill fated Cursed Founding a tumultuous time where chapter gene-seeds were tainted and horribly ravaged the newly found Chapters.
