The opposite of "came end" can be expressed in several ways. One antonym of "come" is to "depart," which means to leave a place. On the other hand, an antonym of "end" could be to "begin," signifying the start of something. Another opposite of "end" could be "continue," which means to keep going or not stop.
Alternatively, you could use variations of these words such as "commence/start" or "finish/complete" instead of "begin/end" to highlight the opposing meanings. These antonyms can help you to express a range of ideas, such as the continuation of a process, the start of something new, or the conclusion of a task or journey.
