Channelworks

Channelworks is a 3-man dungeon that becomes available for entry to players at level 65. It's simple low-level farming or gearing up dungeon that doesn't require healer.

Dungeon was released in Autumn 2013 as level 60 dungeon. Current level 65 dungeon has been out least since October 2015. It has been adjusted numerous times and occasionally removed for that.

Dungeon was referred as "Ancient Underground Waterway" in KTERA patchnote translations.

Lore
Questline given by Dougal in Highwatch as player reaches level 65 has quest to investigate disturbances in sewers in Balder's Refuge.

First boss, the mechanical Sentry AA-23 makes several references to Shandra Manaya "who was inspiration of us all". Images that appear when trap mode triggers seem to be the last boss from Balder's Temple, Meldita from Argon Corpus and Shandra Manaya from Manaya's Core. As Channelworks was added in Wonderholme patch those dungeons were already "old content" and Argon War was officially over.

Second boss's chamber has eastern egg that is part of achievement Putting the Pieces Together. Seek for three little bugs left of entrance.
