Minimalist Sci-Fi Book Cover Design

I’m looking for a dark purple, gothic-literary cover with gold accents. The story is set in the northern mountains/marshes of British India, with a mysterious, eerie and melancholic atmosphere. The cover could feature pine trees, mist, mountains, or a remote railway/forest setting, but keep everything subtle and atmospheric. A faint, ambiguous figure or silhouette could be included. Use deep purple as the dominant colour, with muted antique gold for the title/details. Elegant, slightly vintage typography. No obvious monsters, blood, or cliché horror imagery — the mystery should be implied, not revealed.
