Limitations to know before generating
Generated imagery evokes the aesthetic but does not reproduce specific copyrighted characters, logos, or faction symbols.
Scale and proportion may need adjustment — use explicit size cues and foreground reference objects for best results.
Fine details like inscriptions or iconography will be visually suggestive but not readable or accurate to lore.
Dark atmospheric images may lose detail in shadows — balance mood with enough lighting to preserve composition.
