Zenam is a guy. He's a scientist who is trying to fix the Heart of Llevigar according to the wiki. 
Head Engineer is probably a guy. He is the great grandson of the last person who understood the Heart of Llevigar (The whole thing is that the Heart of Llevigar is very old and no one understands it anymore) according to the wiki.

[1/6] Zenam: Aaah, no no no! This doesn't make any sense, what in the world is going on?! Nothing's working! {frustrated/slight panic}
[2/6] Zenam: Gweh, a visitor? Get out of here! The plant is shut down for maintenance- wait, are you the electromagic expert we're paying for? {confused, hurried}
[3/6] Zenam: You are, right? Right?! Cause we can't wait any longer! This system was supposed to be unbreakable, a flawless design! {desperate}
[4/6] Zenam: We didn't even need to get Corkian consultation on this, we had this system all figured out ourselves, but now nothing's working right! {explaining, frustrated}
[5/6] Zenam: You're seeing all these sparks and hearing all this crackling? We have no idea what could possibly be going wrong with this! That's why you're needed here! {frustrated}
[6/6] Zenam: We don't have much time until full meltdown! There is an entrance to the power plant opposite the bank, go there and meet with the Head Engineer! {hurried/urgent}
--------------------------------------------------------------------------------------
[1/5] Head Engineer: Whew, finally Zeman found a guy for the job. I told him weeks ago this was a two-person task... {relieved}
[2/5] Head Engineer: Wait, it's Zenam? Eh, what does it matter? You knew who I was talkin' about. Lemme give you the lowdown real fast. {realises (first line he says Ze-man here he says Ze-nam), carefree}
[3/5] Head Engineer: About a month ago, there was a big blackout, and the generator here started acting up. Power surges, appliances overloading...heck, some of our lights turned purple! {explaining}
[4/5] Head Engineer: My grandfather and his engineers jury-rigged this whole system. A reset should fix all this, but as a security measure, I need to be here to oversee the reset. {explaining}
[5/5] Head Engineer: So that's your job- get through the system and find the reset button. These holes'll lead you around the generator rooms. Better get going! {explaining}
--------------------------------------------------------------------------------------
[1/5] Head Engineer: Alright, that should do it- Ah, you're back. The system reset just fine, like I said. Everything should be winding down now. {(Like getting up after fixing something), normal}
[2/5] Head Engineer: It's purging the excess energy now- might have a few more power surges and crackles for a while, but it'll go back to normal soon enough. {explaining}
[3/5] Head Engineer: Hm? What, there was a bug in the system? ...what, are you asleep or something? Of course there was a bug, we just fixed it! {confused, snarky}
[4/5] Head Engineer: Well, anyways, Zebra should have our payment all settled. You go on ahead- I still need to stay down here to make sure everything stays smooth. {explaining (Zebra is him mispronouncing Zenam's name again)}
[5/5] Head Engineer: ...oh, it's Zenam? D'you really care about getting his name right, or what? Anyways, the exit's through the water cooling system, it hooks up to the sewer exit. {explaining}
--------------------------------------------------------------------------------------
[1/4] Zenam: Whew...welcome back. The power is back online- Everything is running at full capacity again. I think the system is just running excess through right now. {relieved}
[2/4] Zenam: Glad you got here when you did though- some phony came through saying he was the expert. Clearly he was just here to take your contract money... {normal} (The player took that guy's job)
[3/4] Zenam: Though, I was panicking so much I probably would've believed him... Speaking of which, here's your cut of the pay, and something extra for the trouble. {normal}
[4/4] Zenam: Here's to hoping that the system won't run into any more trouble in the future. I don't want to be faced with an impending cataclysm like that again... {hopeful}
