"More endwise" can be replaced with words that convey a similar meaning. For example, "further along" and "deeper in" both imply a sense of advancing or progressing towards the end of something. "Further along" could be used to describe movement along a path or journey, while "deeper in" could indicate a deeper level of understanding or immersion in a topic. Another synonym is "closer to the finish line," which suggests that the end is near but not quite reached yet. "Nearing completion" is also useful, indicating that something is almost finished and the end is in sight. These words can help to convey a sense of momentum and progress towards a goal.
