"At home most of my work is making squares. Bad idea, here. Are there countries that need more land?"
"That would probably be disastrous in a number of ways. The climate on Earth is very delicate, and disturbing much can have very bad consequences. The spot where you built your mountain was picked with that in mind, and even then, it was because your powers can help against Endbringers much more than that was likely to affect." Legend speaks slowly, at least.
Pause. "Okay. Let's call Harry." He calls Harry, who is still in the building exactly for situations like these, and who repeats what Legend said in a way that's more understandable.
"I see. In my world climate is mostly stable except near mismatched tiles or edges. If I'm not allowed to do anything but fight villains, I should show you how... Calmly? I can capture someone."
Harry translates as best he can, and asks a question about a word in her language at the end.
"Well, patrolling would be a good way for you to understand what parahumans do here, in general. I myself don't usually do it because I tend to have more administrative and PR duties than most other heroes."
"I can take you to him, though Mr. Norton," he gestures at Harry, "will not be able to come with you on patrol and your translator will still take a while to be done."
"If you'll follow me?" And Legend leads her to an elevator that takes her down a couple of levels to a room where a man with a red-and-yellow helmet, red-yellow-white bodysuit with flame-like patterns, and donning on thematically appropriate armor is. "Jetpack, this is Mountain. Would you mind overmuch if she accompanied you in your patrol."
Jetpack looks at her and nods. "Sure, no problem."
"That's fine," Jetpack reassures her as he puts on his namesake. "I'll be going out in about fifteen minutes."
"Yes, but hard. Better with actual rocks, like diamond." She taps her visor. "Or on large scale."
Shrug. "I am Mountain. I will always be Mountain. I see no reason to be someone else."
