Most content at Wikia is licensed CC BY-SA, although there are some exceptions.
 * CC means license is granted to copy and modify it.
 * BY means copies and modifications have to attribute the original.
 * SA means copies and modifications have to be licensed identically to the original, which is CC BY-SA in this case.

The above explanation does not substitute for reading the whole, actual license.

But nothing above means you cannot charge for the copies or modifications. There is a CC license that prohibits that, which is CC BY-NC-SA.
 * NC means copies and modifications can be for only non-commercial purposes.
 * SA in this case means copies and modifications must be licensed CC BY-NC-SA, since that's how the original was licensed.

Some stuff at Wikia is under CC BY-NC-SA. Some stuff at Wikia is exclusively Wikia property. If you want a more specific answer, you should probably hire a lawyer. In the meantime, you're probably okay.
