One of the dangers of the DDC’s fight against the trolls of the Circle of Rot is that if a troll is not finished off, it will eventually come back to literally bite them. Another danger is that nobody yet knows quite what the capacities and resources of the three sisters are. Something that has started to be noticed however is that some of the more unusual trolls have an empowered khyber dragonshard crystal embedded in their chests. One was noted in Vasselack – the spirit troll that slew Lord Bentane Amberhammer. Others have now been seen in a troll that sweated and spurted venom, and another that radiated fierce cold and brought a frost to everything he touched.

Vasselack survived the attentions of mindflayers before being brought into the service of the Circle, but Feerwrack is something far more dangerous. Vasselack is motivated by a mixture of gratitude and rage, but Feerwrack is a believer in the aims of the Circle. He is a fanatic.

Emboldened by the success of Vasselack’s assault on the dwarven stronghold, the Circle looked to find more survivors of the psionic ravages of mindflayer assaults. They were unsuccessful in that, but they were able to further attune their magics with a device they call the Eye of Khyber. Where they found it is unknown for now, but at its heart is an enormous Khyber Dragonshard seething with energies. Fragments struck from this core and bound to the flesh of trolls warps and mutates their already unstable physiologies. Sometimes, rather than grotesques with extra limbs, a truely remarkable mutation occurs – and it is this process that Feerwrack volunteered for.

Driven by his trollish hunger to consume, he passed through the destructive embrace of the machine and came out the other side a virtual twin to Irreck’s lone executioner. At a stroke, Irreck’s assassination capabilities were doubled.

It just remains to be seen where he will place his blades next to shake the core of the DDC
