Twilight Ascendants (12 January 2011)

Feludius, Ignacious, Arion and Terrestra are Twilight's Hammer members who have ascended and become elementals. Feludius of water and Ignacious of fire was the first couple to greet the wolves who enter their chamber. Later Arion of air and Terrestra of earth appeared using lightning storms and quakes.
Together all four merged and formed The Elementium Monstrosity for the last phase. Before its elemental powers become overwhelming, the pack managed to defeat it as well.
