What is an antonym for inscription?
An inscription is the engraving of something into something else such as metal or rock. Antonyms would be delist, expel, or expunge.
There can be many translations depending on the inscriptions. If that metal is a sword, it can be the name/title of the warrior or a small inscription of his favorite saying. Just like you cannot ask what a general inscription on a plastic means without any context, you cannot ask what the literal Chinese translation of a (generic) inscription is without the proper context.
The first inscription you see are directions. They read: Top right, lower left, top right, top left, top left, lower left. Following these directions gets you to the next inscription, as well as some items. The other inscription reads: Friendship all lives tough other lives to create something anew and alive. I presume that this inscription is linked somehow towards Team Galactic, however since I can't remember if there is a part in the story…
