Night-enshrouded is a beautiful word to describe the darkness and mystery of an enveloping night. However, if you are looking for synonyms to diversify your writing, there are plenty of options available. You can use "darkened" to convey a similar mood with a simpler word. "Shrouded in darkness" or "wrapped in nightfall" also work well. "Obscured in the night" adds a more mysterious feel to the phrase. For a more poetic option, you can try "enveloped by the nocturne" or "cloaked in the twilight." Whatever synonym you choose, it's important to capture the essence of the night and leave your readers spellbound.
