This sentence is complex.
Complex sentences consist of a dependent and an independent clause, as is the case here. The dependent clause is <em>After some time passed, </em>and the independent one is the rest of the sentence.
A simple sentence would have only one independent clause, and a compound sentence would have at least two independent clauses.
