Clunk is one of Phoenix Ascension's officers on the Emerald Ocean, and a Zarquon alt.

Having accidentally memmed a league point during a Navigate with the Navy mission on 9th May 2020, in a fit of Obsessive-Compulsive mania, set about memming the entire Emerald Ocean, and graduated from the Zarquon school of Navigation in the early afternoon of the 5th June 2020, having completed the final league point somewhere near Scurvy Reef. When quizzed, he replied "Zzzt rrpp eep plplplplbb zzooot eeeup" which was translated into "It was something to do during lockdown". We don't yet know if 28 days is a record, but it's an achievement nonetheless.
If you can find him, he will chart you pretty much anywhere, usually for free.
