The land of Ireland lay empty after Parthalon’s passing for thirty years before another group of people arrived, led by Nemed, who was a distant relative of Parthalon’s.  These people made huge change to the landscape clearing twelve plains and firmly marking their presence on the land.  Nemed had set out with thirty four ships, each crewed by thirty over a year previously.

Near the start of their voyage, the Nemedians came upon a tower of gold jutting up out of the sea, covered by sea water at high tide and laid bare by the sun’s rays at a low ebb, they were inflamed by greed at the sight of it and assaulted the Tower of Gold.  So intent were the Nemedians in taking the tower they did not notice as the sea began to rise around them sweeping their boats away and through their greed and inattention all but one ship was lost and most of Nemed’s men were drowned.   he managed to get all of the women on to the remaining ship however and arrived in Ireland with his four sons and a good host.  When they arrived four new lakes burst forth as a sign of their welcome.  Nemed’s wife, Macha, was the first of his company to die in Ireland and was buried in a place called Ard Macha, after her.  Nemed and his people had to fight against the Formorians just as Parthalon had but these were not bloodless, magical battles.  The Nemedians fought fiercely and slaughtered two great Formorian kings, Gann and Sengannn.  The Formorians were so enraged by this that they attacked the Nemedians on two later occasions and though Nemed and his people won both battles, the losses were heavy and the hatred on both sides only grew.

As well as the great work of clearing twelve plains, the Nemedians’ built two royal forts, setting in place foundations and structures that were vital for the enduring wellbeing of the people. One fort was built by Nemed’s people and the other by four Formorian brothers who dug the whole royal fort in one day but before the sun rose the next day, Nemed killed the four brothers so that they would not improve upon the fort that they had built for him.

Nemed’s people thrived in Ireland for many years but a plague came upon them and killed two thousand of their number with Nemed himself among the dead.  The Formorians saw their chance to strike at the Nemedians while they were weakened by this tragedy and took over Ireland making it a vassal state and imposing huge taxes on the people.  Two thirds of their corn, their milk and their children had to be delivered every year on Samhain to the Formorians, who were led by two kings, Morc and Conand.   The anger and sorrow grew in the hearts of the Nemedians until they could bear it no longer and gathered together to attack the Formorians.  With thirty thousand at sea and thirty thousand in ships they assaulted the Tower of Conand  on Tory Island and took it by force.   But Morc arrived with reinforcements and the magic of the Formorians caused the sea to rise.  Distracted by their battle fury the Nemedians did not notice the water rising and almost all of them were swept away and drowned.    A few survivors managed to escape on the last ship.  They split up going their separate ways.  A few returned to Ireland but the plague finished them off.  Though the women lived on a few decades longer than  the men.  A small group of them went into the north of the World where they found great wonders.  A second group led by Nemed’s son, Fergus Redside and his son, Britton Wayle went to Scotland and Britton Waye faired so well there, that the whole island was named after him.  The final group, led by Nemed’s grandson, Simeon, went to Greece where they were captured and enslaved, living under great hardship for many years.
