Prologue---

Superman was sitting at the console, feeling a bit bored. True, one shouldn't wish for people to be hurt, but it would be nice to have some action, even if just this once.

As if by some quirk of fate, the emergency contact light glowed. Brainy, beside him, immediately turned on the viewscreen.

"Brainiac 5, of the Legion of Superheroes," He said.

"This is Tylew Randor, President of the Interdenominational Bank on Elindor," a man with gray-white hair said breathlessly. Brainy could hear the others enter behind him, almost silently.

'Bank on Elindor' was one way to say it, but as Brainy remembered, another way of saying it would be the Bank IN Elindor, as the entire planet was one gigantic maze of vaults and currencies.

"We have had mass break-ins in the past few days, and hundreds of thousands of vaults have been completely emptied!" Randor continued. "The strangest thing is, the intruder has emptied the most secure and full vaults. He's been working his way up, and I'm beginning to get worried, as our security has had no luck in stopping him. So, we've decided to come to you for help."

"We'll be there," Brainy promised, and turned off the viewscreen. He spun around and faced the group.

"Well, the first question that comes to my mind is this," Superman said. "How did this guy know which vaults were more protected, and which ones had more in them?"

He had a point. "Exactly," Brainy began. "The vaults are not arranged in any specific order, because they are intentionally placed at random."

Lightning Lad raised an eyebrow. "So, how does that effect Superman's question?"

"It means that while one very important vault may be placed next to an unimportant one, another vault may be surrounded by two other important vaults. It all depends on the placing."

"I still don't get it," Lightning Lad said.

"If the vaults aren't arranged by any sort of order, how do you know whether or not you're getting valuables or someone's old gym clothes?" Brainy pointed out, annoyed.

"Exactly!" Superman said.

"Hmm," Timberwolf murmured. "Also, how does this person get past security personnel, and how would they know where other security devices are?"

"And, if they have superpowers, who's to say they can't just look through all the doors and figure out what to steal and where security is anyway?" Saturn offered.

All valid questions, to which no one had any real answers.

"Well, I suppose we should get going, because the sooner we investigate, the sooner we get answers," Superman said.

"There's only one problem, Superman," Brainy said.

"What's that?"

"Elindor orbits a red sun."
