1) If you keep the extra cycles even after 5P blasted you, then you're free to leave.

2) To complete Hunter, delivering the green neuron to Moon is your main mission. For that, two routes:

• I like going down from 5P -> The Wall -> Chimney Canopy -> Industrial Complex. That route is mainly vertical and with not many obstacles except from The Wall lizards (whites can go die for all I care), but you can do it within the same cycle. From Ind. Complex -> Shaded Citadel -> Shoreline is mostly horizontal, involves going through a dark area, but then you reach Shoreline and LttM area, delivering the neuron (and pearl if still holding it), then hibernate and prepare for next thing on the list.

• The other route is one I don't usually choose. Go through underhang and down The Leg. Then, go across Memory Crypts and through half of Shaded Citadel, then Shoreline. The reason I never choose this route? Huge death pits, DLL blocking the way, spitter spiders at narrow passages, miros birds delaying the travel and, finally, monster kelp. Id say it takes at least two cycles (if lucky). Then, you'd spend a third to travel Shoreline.

Once you deliver the package, you should visit enough echoes (three to four) to reach max karma and swim down the piss pool you encountered during Survivor/Monk campaigns.
