By the way, considering Croteam's passion for ancient cultures, I think through Mordecai the Summoner (keyword: Mordecai - Jewish masculine name of Persian origin comes from the name of god Marduk, means "servant of Marduk") we can come to really quite accurate impression about who is MENTAL exactly, or how he might be called in the ancient Mesopotamia - MARDUK.
For the first time in known history character named Mordecai appears in the Tanakh (Old Testament)
Together with his cousin Esther, who became his adopted daughter, he became the savior of the Jewish people from Haman's wiles.
By the way, i figured how Mordecai from Borderlands could become so bright... i guess i filled him with ultra-purified Argent plasma. kek
