A bit later than I was hoping, but here's Volume 2
What Happens
The Guardians of Desire, Chapter 2 & 3
The physician reveals himself to be Vargas, formerly the personal physician of the Count, and tells the story of how the Count obtained the Behelit, and how he became the way he is. Seven years ago the Count, always a cruel man, came into possession of the Behelit, supposedly by chance, and became truly monstrous. He subjected prisoners to horrendous tortures and began to eat their flesh, his quest against heresy no more than an excuse to acquire fresh victims. Wanting no part in it, Vargas tried to flee with his family, only to be caught, mutilated, and forced to watch the Count eat his family. Feigning his death with a concealed poison (where, I wonder?), he managed to steal the Behelit and escape, but despite seven years studying religion and the occult he has been unable to deduce its purpose – which Guts promptly explains. The Behelit is a key to another dimension, the means to summon demons who have manipulated humanity from the shadows since ancient times – the five members of the Godhand…
Meanwhile, Zondark, the captain of the guard, has lost his eye in the recent fight with Guts and hungers for revenge, which he is offer the chance to do after receiving a rather disgusting boon from the Count. Back at the laboratory, Puck examines the Behelit curiously, only to discover it’s alive. Vargas shows Guts a map of the castle and a secret passage, begging the former to avenge what the Count has done to him, but Guts rebuffs him; he’ll kill the Count, but only because it suits his own purposes. Zondark bursts into the hideout and proves to have become something other than human when the dismemberment of his right arm results in an alien, tentacle-like appendage growing to replace it. The new limb is able to swing his battle-axe with blinding speed, and Vargas and Puck look on in awe as Guts seemingly blocks every blow. The loss of half his head proves to not be much of a deterrence either when the Count-faced demon the latter gave to Zondark emerges from the wound to taunt Guts and Vargas, but the former cuts some ceiling beams that trap Zondark, knocked-over candles setting the lab on fire as the rest make their escape.
Emerging from the sewers, Guts rudely takes the Behelit from Vargas and heads off to confront the Count. After exchanging some kind words with Vargas Puck follows after and chews Guts out for his ingratitude, but the latter insists Vargas would just be a liability. Meanwhile, the still-living Zondark captures Vargas.
At Vargas’s execution, Puck sees Guts hiding nearby and thinks he’s come to rescue Vargas, but the latter, using the pretext that it’s a trap for him, insists he won’t, that this is the price Vargas has to pay for trying to oppose someone more powerful than him. Puck isn’t convinced and insists Guts is afraid he’s just like Vargas – caught up in something far over his head. Puck makes an attempt to save Vargas himself but only succeeds in bouncing off the headsman’s axe. Before his death, Vargas predicts that the Count will pay for his crimes and be dragged to Hell by his many victims.
