Route 205
After about half an hour, a woman in uniform arrive, on the back of a Braviary. "Major Kaufman," she says, saluting the muscular men directing the operations. "Here's the three pokéballs the suspect had. Two are confirmed to be holding her pokémon. The third on is registered to her, but empty."
The Major takes the ball from the woman, nodding. "Let's hope we're right then..." As you watch, he brings out a Bouffalant, rides it toward the river. The giant Omastar is still sitting there, occasionally tossing rocks at the various SPT pokémon surrounding it (from a mostly safe distance). It seems their strategy was to just attack the Omastar from the back if it tried leaving the river, luring it back in the middle.
Reaching the line, the Major commands the rest of the SPT to give him cover, as he gets close enough to use the pokeball. The Omastar starts glowing red, though it looks less... stable than the usual recall of pokémon. Still, the giant beast vanishes, causing the Lieutenant to breath a sigh of relief. "Looks like that did it. Time to wrap up." Turning to you, he adds "Your pokémon are on their way back on a helicopter. We'll give you a lift to Vinmur, you deserve some rest after all this."
