There's a small niche in the mountain directly south of the castle. Search it for a Duplicator. Also search in the circular shrubby area to the east for a Bullet Charge. You'll find the town of Halmetz to the northeast.

Your team will automatically start talking as soon as you enter Halmetz. Ashley suggests you search the town, so your team splits up. No sign of life can be found. Suddenly the bell tower rings. Brad thinks it's a trap, and Ashley rushes over to push Lilka out of the way of an explosion. Judecca appears on a nearby rooftop and introduces himself. He casts a ball of energy at your party, forcing them into a fight.

Just keep hitting him until Judecca intervenes. After the fight, Trask will cover everything in darkness. Ashley hears his beast inside speak, and he can't fight it off. When the darkness clears, Trask is gone and your group is unconscious. Judecca isn't sure what's happened, but that doesn't stop him from tossing your group into a cell in Golgotha Prison.
