It's Luce.
Everything is awful.
-- Cassandra
There was nothing we could do but fight. Luce... whatever he was, was accompanied by over a dozen undead creatures. Even if we ignored him, they would be a problem.
Brom turned, in fear, as Luce disappeared into the ether. Reappearing not five feet from him, he shared the look Brom did -- undying and vengeful. Brom felt a magic pull at his form, but he and the Hollow Spirit refused.
Brom and Eragon fumbled around to find Cassandra and Fathom respectively. Eragon conjured a dimension door for himself and the tabaxi monk; Brom pulled Cass with him with a thundrous step.
Cassandra noticed that Luce did not have his sword -- we had lost it, but he didn't have it either.
Brom tried, with Cassandra's help, to reach beneath the veil and feel for Luce's spirit. He... failed.
And neither could he feel Sully or Ianthe. "They're not there."
Cassandra banished Luce, and we tried again to invoke Luce. Again, to no avail. In panic, Cassandra pulled the weave and fell into it, teleporting away from the chaos. But as she left, a fell blade caught her shoulder, and the banishment. Luce reappeared, and unable to find Cassandra, Brom was his next target. The two became locked in combat, dueling to the (un)death.
Eragon regained strength, casting slow at the zombies (and Luce) attacking our group.
It wasn't until Rohrouk engaged Luce that the ghost spoke: "You left me, Rohrouk."
This, along with Cassandra reappearing on shore, angered the ghost. Luce disappeared as he seemed to head towards the wizard onshore.
Eragon almost died, as the Hollow Spirit shattered a ghostly limb to protect him from the ghosts' onslaught. "I'm not losing anyone else!" Brom resounded. Even as he felt ghostly claws hold him fast, he and the spirit within resisted. No.
We reduced them to two, Luce and his wraith companion.
Cassandra: "I love you, and I'm sorry."
It occurred to Brom that the Hollow Spirit could reach out to Luce as it did to him: "Can you save him?"
The response was almost immediate. "I do not call the dead. I am the dead. This thing is gone."
Eragon was the one to end the fight, with a concussive strike of arcane energy to his form (synaptic static). The boat was quiet as his form staggered back. We all heard the voice boom out. Deep, reverberating, and familiar -- him. "He'll come back."
It was over.
