Yeah, that plotline has moved along quite a bit. Dies and Saves a Fox got to the bottom of the dungeon, and found an ogre being tortured by demons who own its soul. Dies Horribly decides it's time to live up to his name, so he sells his soul to a demon hoping that Saves can get out with the orb that the demons are guarding. The demon kills dies to claim his soul, but it also claims a soul in Dies' metal arm (which we were explicitly told shouldn't have a soul of its own), and the demon is banished for breaking its own agreement. Dies is brought back to life, and he, Klik, and Saves defeat the demons with the help of the now-freed ogre. Dies' arm takes over his body for a part of the fight - it is both very dangerous and very rude.
They escape the dungeon find the Viper Clan waiting for them. The Vipers lead the ogre away, claiming they're letting him leave. He sees this is a trap, but still can't avoid the monster they lead him to, a huge switchbeast. Meanwhile, the Vipers prepare a ritual for Dies, Saves, and their other goblin captives. Duv, the Viper leader, offers to make each goblin the chief of their clan so they can unite the clans under Viper rule. Dies and Saves refuse her offer, and Duv orders them to be killed.
The ogre sneaks back into the Viper camp, having escaped from the switchbeast alive but wounded, and steals some healing potions. Then he heads into the middle of the Viper camp, where they're about to kill Dies and Saves, and starts killing Viper goblins. Then the switchbeast finds the camp, presumably having followed the ogre, and chaos ensues. In the conflict, Duv and Saves a Fox are both knocked off a cliff, with the orb from the dungeon. Duv slows her descent with her wing, and Klik grabs Saves just before she hits the ground. Klik changes into a staff and Saves uses him to fight Duv.
Back on the cliff, Duv's son Grem walks out of the dungeon, where Dies and Saves left him for dead. He immediately attacks the ogre who is slaughtering his clanmates by the dozen. The ogre is stronger, but Grem has a finger from the finger horror, and manages to infect the ogre's foot with the gross melting body thing. The rest of the Vipers rush to defend Grem from the ogre and, down a foot, there's no way he can beat them all. So he amputates his leg at the knee to stop the infection from spreading, stuffs the rest of the stolen healing potions into his mouth, chews a few up to heal himself, and jumps off the cliff.
Nearby, the goblin captives have decided that they need to kill Dies or Duv will kill them all when she gets back. They start beating him, but his arm takes over again and kills them sadistically. The green metal starts covering more of Dies' body, and it steps over to the cliff face to search for Saves below. Dies senses that it wants to hurt her, and manages to regain control of his body for just long enough to amputate his arm.
Back down the cliff, Saves is losing her fight and about to die when the ogre lands on Duv. He gives Saves a potion, she heals, takes the orb, and runs off to find Dies. The ogre finds Duv, picks her up, and decides to lecture her about all the death she's caused. He decides the best solution is for her to give up on her obsession to restore her lost wing, so he rips off her remaining wing and walks away.
Back up the cliff, Dies' arm has turned into an evil green demon Klik. It starts to attack Dies, but Klik flies up the mountain and starts fighting it. Saves finds Dies bleeding on the ground and shoves the orb at his wound, figuring that if it can help restore wings, it can help restore arms. It works, and Dies now has a green glowy magic limb. He watches the green Klik that used to be his arm throw Klik into a pool of blood, which corrodes it. Dies charges in to save Klik, and discovers that the evil green Klik is corroded by his new arm. It jumps off the cliff to escape. Dies rushes over to Klik, who is now almost completely corroded, and can do nothing but hold Klik in his arms as it crumbles to dust.
I don't think we've seen Dies since then, and that was in 2012. Pretty understandable if you've forgotten some or most of that. Hopefully we'll get back to him soon. Forgath seems like he might meet up with Dies at some point, since he's like 60% klik body parts now and is hunting another evil klik.
