They had run all over the galaxy trying to piece together the mystery that was the Leviathan. They were nearing the end of their journey, finding a trace of the Leviathan's energy signature on Desponia from a probe they sent down. They were now following in the shuttle, debating the best course of action when a strange pulse of energy sent them spiraling to a shipwreck below. Shepard, Javik and James hesitantly investigated the eerie hulk, dispatching husks as they went along.
"You always take us to the nicest places, Lola," James said as the last husk fell.
"I thought you could use a reward for all your hard work," Shepard responded.
"Commander," Javik warned and gestured up toward the reaper sliding down from between the clouds.
"Shit," she hissed as Cortez buzzed in over the comm. They ran back to the shuttle to offer what support they could while he finished the repairs. With a whoop from the piolet, the engines roared to life and the shuttle lifted off the ground. The three still on the shipwreck pulled back to allow Cortez to fire freely. He was able to make one pass before another pulse of energy knocked the shuttle back down.
"Of course it lands on the other side," Shepard said as she rolled her eyes and reloaded. They took off once again, plowing their way through the reaper forces.
"Check out that mech!" James called. The mech in question was large and unseemly, safely held behind a door they had no hope of opening since the wreck had no power.
"Looks ancient."
"It's a diving mech," Cortez informed them. "That might be your best bet to get down to the Leviathan."
"I thought you said the shuttle can dive?"
"The specs say it can, but it's a no go. That last pulse damaged it more that I can fix here."
"Options?" Shepard yelled over the gunfire.
"Call the Normandy!"
"The pulse will hit it, too. Then we'd really be stuck."
"Take the power cells from the shuttle to juice up the wreck. Once there's enough power to open the door, take the mech." Cortez offered.
"That sounds like our best bet. Let's get a move on!"
Power cell strapped to her back, Shepard took off at a sprint to the nearest socket and shoved the cell in, beating back a marauder while it charged. After a marathon of killing, running and charging, the door finally hissed open and she climbed lithely into the mech, using it to wipe out the remainder of reaper forces before meandering it over to Cortez.
