==History==
The [[Master]] was trapped in a [[Plodex Ship]] for 40,000 years as his body became integrated into the ship systems preventing him from escaping. Over the many years spent in the [[Plodex]] ship's experiments, Eshu became more intelligent, and he learned to tap into the ships systems with his mind, eventually taking them over altogether; he was however unable to leave the ship. He created a plan 5,000 years ago and sent out a signal to [[Marrina]], herself a member of the [[Plodex]] race, which brought her and [[Alpha Flight]] with [[Invisible Woman]] and [[Sub-Mariner|Namor]] behind her. Knowing something of [[Alpha Flight]]'s potential, Eshu, now calling himself The Master Of The World, planned on using [[Marrina]] as bait, to have them destroy enough of the ship to allow him to escape in a submarine

The submarine is independent and self-sustaining and could be controlled with the [[Master?s Helmet|Master?s helmet]], and thus became the Master?s new mobile base of operations. With the ship the Master traveled to Lake Ontario where he captured [[Marrina]], [[Puck I| Puck ]] and Namor and was going to use Marrina to mate with a surviving [[Plodex Mate|Plodex male]]. However, thankfully Puck and Namor tricked Master and ended up severely damaging the ship causing it to sink to the depths of Lake Ontario. The Master remained until awoken by [[Llan]] and the submarine was never seen again.
