Session 14+15+16+17+18+19+20 - Aldrek's Grave

As you continued through the icy caves, you dealt with small caves where goblinoid ice creatures built tunnels to travel around. Eventually the group entered an icy cavern where people were frozen as ice sculptures. Here they fought the Vossen Sisters of the Crags.
  After clearing the ice hags, they followed up on the Zephyrn Fleet, led by the Cloudburst Mage Aurora Beaufort. They are resting near an old black drakaar ship that rested in this cave after a journey up the Slipstream that divides the island.
  Defeated the guards but let a snowy horned owl escape. Found some old journals from the ship captain from way back in the early Fourth Era. Cicero Windslayer was a famed dragon slayer and this was his ship.
  Entered the resting place of Keldrith's mate, Aldrek of the Storm. He was long ago killed while fighting the many eyed serpent and laid to rest here. The Shatterbrand stops the Zephyrn Elite and the Cloudburst Coven from extracting power from the dragon eggs in a dark ritual to bring back the husk of Aldrek to fight for them against Keldrith. As the battle ended, Gnarl was entranced by the necklace he stole from the bag. He placed the amulet in the missing runic slot on Aldrek. This power surged through him and his body began to wake up. The storm began surging and the cave began to fill with water. As the water level raised the group fought against the husk of Aldrek. After a long, arduous battle where many people almost died, Aldrek was defeated when it tried to escape into the water and Sossari held the water, freezing it in place. The impact of Aldrek hitting the frozen water spread his bones across the icy surface. They secured the amulet again and kept it safe but the water was still filling the cave. The team quickly used a teleportation circle to escape back to the Gobsnapper.
