Cap 847: A memory of happiness and pain

Pov of a cultist: 

I look at chains with the thickness of a Human's body, these chains were previously invisible being made of pure multicolored energy in flow taking the form of chains, but now these chains were very visible, there are 8 chains of which 2 have already been broken if turning crystal shards on the ground. 

Now one of those 6 remaining chains has become completely red and solid like some kind of metal with screaming faces popping out at times. 

"How much longer will it take?" (I) 

"The job is done, now we're going to need the Lord of Shadows to break the seal." (Shadow Slave) 

"It won't be necessary, he's busy with other plans, I'll do that myself." (I) 

"You'll need a special weapon for that, if you touch it directly you'll be contaminated by the curse." (Shadow Slave) 

"I'll get what I need, there's a Cursed Weapon that belonged to a Hero in the past, I know where it's sealed and I'll get it." (I)
