It's a filler arc. The anime is not ending any time soon. They just introduced Hades and he won't play a role for a considerable amount of time. They are probably going to add some backstory to the guild before the Edolas arc since it's probably the longest FT story arc and much of the guild doesn't play much of a role.

We'll probably get some filler involving Juvia, Levy, Mirajane, and others.
