The Otherknown is a science-fiction webcomic about found-family, time travel, and wisecracking robots! …Well, mostly just the one.
Chandra and her wealthy aunt are on a mission, and chronotite, the most valuable mineral in the galaxy, is at its core. One sliver of it enables faster-than-light travel; but only through space, not time, despite the name.
Their plan is simple enough to start with. Too bad things tend to go south quickly whenever an intergalactic criminal syndicate is involved.
The comic updates every Wednesday/Saturday, with planned hiatuses between chapters usually about a month in length.
