TotEM : Port Nyanzaru (Patreon)

Over 100 ai-generated images themed to the seaside jungle city of Pport Nyanzaru from Tomb of Annhilation. Categories include:

arena, bridges, cellars, harbour, jungle ruin, markets, palatial, prison, restaurants, ritual altars, rooftops, sea caves, sewers, shops, streets, taverns and a single image of the Tower of Sune. 

Their style isn't consistent - some are very painterly and suggestive and others more "realistic". They can never be exactly the location you're describing, but hopefully as thematic mood enhancers -or- used as totem locations to place minis/tokens on, they should spark the visual storytelling.

Enjoy.
